COMPARISON: MRI pituitary, 11/21/07 and CT head, 12/20/07
FINDINGS:
As before, patient is status post transphenoidal approach for residual
right pituitary macroadenoma. Postsurgical changes are present within
the nasal cavity, sphenoid and sella region related to recent
resection. There is subtle enhancing soft tissue convexity along the
right posterior aspect of the sella which likely represents
post-surgical changes and less likely residual disease. Expanded sella
with a fenestrated like appearance of the infundibulum remains
unchanged.
Scattered subcortical hyperintense FLAIR signal in the supratentorial
white matter remains unchanged. New area of hyperintense FLAIR signal
within the right midbrain is due to wrap around artifact from ear.

As identified on the previous MRI, there are several focal areas of
increased flair signal within the right frontal periventricular region.
These are relatively unchanged in size and appearance from the prior
examination. The gyri and sulci are normal in appearance. There are no
areas to suggest migrational abnormalities. Cerebellar atrophy is
stable. The hippocampi are well visualized. There appears to be mild
volume loss on the left which is slightly more prominent than on the
prior examination. No areas of abnormal enhancement.
IMPRESSION:
1. Stable cerebellar atrophy.
2. Mild assymetry of hippocampi, with the left less than the right.
Although it is more prominent on today's study, it is likely reflective
of imaging TECHNIQUE and not pathology progression.

CEREBRAL ANGIO ñ DIAGNOSTIC FOR MASS
------------------------------------------------------
EXAM: Cerebral angiogram.
HISTORY: Cerebellar lesion, ataxia.
COPARISON: MR Brain 9/18/2007.
PROCEDURE:
Written informed consent was obtained from the patient after
a lengthy discussion of the risks and benefits of the
procedure. Risks discussed included but are not limited to
bleeding, pain, infection, vascular damage, allergic
reaction, and stroke. The patient was brought to the
angiography suite, placed in the supine position, and prepped
and draped in the usual fashion. Conscious sedation was
administered by the Radiology nursing staff.
The right common femoral artery was punctured using an 18
gauge single wall needle. Using Seldinger technique a 4
French sheath was inserted. Vessels, left CCA, right
vertebral, and right CCA were selectively catheterized using
a Glidewire and 4 French vertebral catheter. Selective
injections in multiple projections were performed in each of
these arteries. The patient tolerated the
procedure well without complication. The catheter
and sheath were removed and hemostasis was obtained with
manual compression. The patient left the angiography suite
neurologically unchanged.
I, Dr., the attending neuroradiologist, was present for the
entire procedure.
FINDINGS:
Right common carotid artery: (PA, Lateral). Normal terminal ICA. Normal
anterior and middle cerebral artery branches, with similarly
normal capillary and venous phases. No aneurysm or other
vascular anomaly. No vasospasm. No significant vascular
contribution to the posterior fossa.
Left common carotid artery: (PA, Lateral). Normal terminal ICA. Normal
anterior and middle cerebral artery branches, with similarly
normal capillary and venous phases. No aneurysm or other
vascular anomaly. No vasospasm. No significant vascular
contribution to the posterior fossa.
Right vertebral artery: (lateral, Townes ). A large, ovoid area of mild
vascular blush is present within the posterior fossa adjacent
to the tentorium correlating to the ring enhancing mass seen
on the MR examination. There is no enlarged vessel supplying
this area of blush. There is no arterial venous shunting
through this area. There is no significant contribution to
this area via collaterals from the anterior circulation.
Otherwise normal right vertebral and basilar artery. The
dural sinuses are grossly patent.
IMPRESSION:
1. Large, ovoid area of mild vascular blush within the
posterior fossa adjacent to the tentorium correlating with
the ring enhancing mass seen on the MR examination. No AV
shunting is detected. There is no enlarged vessel feeding
this area. There is no collateral blood flow from the
anterior circulation.

CEREBRAL ANGIO ñ TUMOR EMBO
--------------------------------------------------------------------
EXAM: Diagnostic cerebral angiogram and embolization
HISTORY: Recurrent gliosarcoma around left ear and neck.
Preoperative embolization.
COMPARISON: Brain MRI, 3/12/07
PROCEDURE:
Informed consent was obtained by the patient and placed in
patient chart. Patient was brought to the angiography suite
and placed supine on the table. General anesthesia was
administered. Right groin was draped and prepped in sterile
fashion. Using seldinger technique an 18 G needle was used
for vascular access in the right femoral artery with
placement of a 4 Fr sheath.
Using a 4 Fr Vertebral catheter and .035 glidewire,
diagnostic cerebral angiogram was performed with selective
catheterization of the following vessels: Right CCA, Left
vertebral, Left ICA and ECA. Using a .014 Excelsior
microcatheter and Synchro wire, selective catheterization of
the left posterior auricular and occipital arteries were
performed and embolization performed using 250-350 micron PVA
particles. Sheath was pulled in angiography suite
with no complications and patient was transferred to
PACU.
I, Dr. , Neurointerventional Attending, performed the entire
procedure and was assisted by Dr. , Fellow
Neuroradiology.
Findings:
Right CCA: There is normal filling and appearance of the ICA,
ECA and distal branches. No aneurysms, AVMs or occlusion.
Normal arterial, capillary and venous phases. At the junction
of the left transverse sigmoid sinus there is focal narrowing
which may be related to intracranial tumor compression. There
is prominent nasal blush of unclear clinical
significance.
Left ICA: There is normal filling and appearance of the ICA
and distal branches including both A2 segments. There is a
left fetal PCA origin. No aneurysms, AVMs or occlusion. There
is normal arterial and venous phases with hypoperfusion on
the capillary phase in the left parietal angular region which
may be related to prior resection or infarct. As before,
there is focal narrowing at the junction of the left
transverse sigmoid sinus, but sinus remains patent. There is
reflux into the ECA and branches.
Left ECA: There is normal filling of the ECA and branches.
However, the superficial temporal artery is not visualized.
There is tumor blush in the left temporal occipital region
supplied by collateral branches off the STA, posterior
auricular and occipital arteries. Left Vertebral:
There is normal filling of the left vertebral artery, basilar
and right PCA with reflux into the right vertebral artery.
There is no filling of the left P1 segment due to fetal PCA
origin. Normal arterial, venous and capillary
phases.
Left CCA (post-embolization): There is mild persistent tumor
blush along the anteroinferior left temporal occipital region
via small branches off the occipital artery in proximity to
the vertebral artery anastomosis; otherwise previous tumor
blush supplied by the posterior auricular artery has been
successfully embolized. Incidentally noted is a small plaque
in the proximal left ICA just distal to the bifurcation, but
with no significant stenoses.
IMPRESSION:
1. Successful tumor embolization via the left posterior
auricular and distal occipital artery branches with mild
persistent tumor blush along the anteroinferior temporal
occipital region from small branches off the occipital artery
in proximity to the vertebral artery anastomosis.
2. Focal narrowing at the junction of the left transverse
sigmoid sinus may be related to intracranial tumor
compression, but no sinus thrombosis.
3. Small plaque in the proximal left ICA just distal to
bifurcation with no significant stenoses.
4. Left fetal PCA origin.
Findings were discussed with Dr. Rostomily immediately after
the embolization.

SPINAL ANGIO
---------------------------------------------------------------
EXAM: Spinal angiogram with embolization
HISTORY: Metastatic squamous cell cancer with vertebral mets involving
T7 and
T8; anticipating surgery; pre-operative embolization.
COMPARISON: MRI of the spine from February 12, 2008.
TECHNIQUE:
The risks and benefits of the procedure were discussed with
the patient and written informed consent obtained.
The patient was brought into the Angiography suite and
general endotracheal anesthesia was provided by the
Anesthesiology Service. Bilateral groins were prepped and
draped in standard sterile fashion. The right common femoral
artery was punctured using a single wall 18-gauge needle. A 5-French
sheath was then placed using Seldinger
technique.
A Chuang-II catheter was then utilized over a glide wire to
select the following vessels: Left T6, T7, T8, and T9, and
right T7, T8 and T9 intercostal arteries. Following this, the
catheter was then used to select the right T7 artery.
At this point, a Renegade microcatheter was used with the
help of a Synchro-200 guide wire to select the distal right
T7 artery followed by embolization with PVA particles
(250-350). Following this, a Tornado coil was
deployed into the vessel. The right T8 intercostal artery was
then similarly selected using the Renegade microcatheter and
embolized using PVA particles followed by a single Tornado
coil. The microcatheter was then used to select the left T7
artery followed by the deployment of a single Tornado coil. The
catheter and sheath were then removed followed by manual
compression and hemostasis. There were no immediate
complications.
I, Dr., the attending radiologist, was personally present for the
entire procedure.
FINDINGS:
LEFT T6 (AP): No vascular blush noted. No aneurysms or
vascular malformations.
LEFT T7 (AP):In addition to prominent vascular tumor blush
involving the T7 vertebral body, there is also supply to the
posterior left spinal artery which fills cranially.
LEFT T8 (AP): Prominent tumor blush noted involving the T8
vertebral body. In addition there is supply to the artery of
Adamkiewicz.
LEFT T9 (AP): No tumor blush noted. No aneurysms or vascular
malformations.
RIGHT T9 (AP): No tumor blush, vascular malformations or aneurysms.
RIGHT T8 (AP): Faint tumor blush involving the T8 vertebral body noted.
There is no evident spinal arterial supply.
RIGHT T7 (AP): Faint tumor blush noted involving the right T7 vertebral
body. There is no evident spinal arterial supply.
IMPRESSION:
Endovascular embolization of the right T7 and T8 thoracic
intercostal arteries with particles and coils, as well as
embolization of the left T7 intercostal artery with a single coil. The
left T8 intercostal artery is also associated with a
prominent tumor blush; however, this vessel was noted to
supply the artery of Adamkiewicz and was therefore not
embolized.
Above findings were discussed with the Spine service
immediately after the procedure.

VERTEBROPLASTY
--------------------------------------------------------
This patient is a participant of the INVEST study, a randomized study
of vertebroplasty and as a result does not know if an actual
vertebroplasty was performed. All persons reading this report should
take care to prevent informing the patient about the information
contained herein for one year following the date of this report.
HISTORY: L1 compression fracture.
EXAM: L1 vertebroplasty.
COMPARISON: MR lumbar spine 12/17/2007, plain radiographs of the
lumbar spine 12/17/2007.
TECHNIQUE: Written informed consent was obtained from the
patient following a lengthy discussion of the benefits and
risks of the procedure. All questions were answered. The
consent was placed in the patient's chart.
Following this, the patient was brought to the angiography
suite and placed prone upon the examination table. The
patient was prepped and draped in the usual sterile fashion.
The L1 vertebral level was identified and targeted using
fluoroscopy. The soft tissues above the left pedicle were
anesthetized using lidocaine via a 25G needle and
subsequently a 22G spinal needle. With a transpedicular
approach, an 11 gauge needle was placed into the lateral
aspect of the vertebral body under fluoroscopic guidance with
position confirmed under lateral and frontal projections.
This entire procedure was repeated with the patient's right
L1 pedicle. Methymethacrylate was mixed and injected through
both needles under direct fluoroscopic visualization,
eventually opacifying the bilateral paracentral aspects of
the vertebral body. Both needles were removed. The patient
tolerated the procedure well with no immediate
complications.
I, Dr., the attending Neuroradiologist, was present for all
portions of the procedure.
FINDINGS: L1 vertebral compression fracture with
approximately 30% vertebral height loss. 4 cc of
methylmethacrylate mixed with barium was injected (2 cc
through each pedicle). The distribution of the cement was
observed under fluoroscopy. There is good bilateral
distribution of cement. A small amount of cement
extravasation is seen into the prevertebral soft tissues.
Cement within the posterior aspect of the L1 vertebral body
also approximates but does not appear to enter the central canal.
IMPRESSION:
1. Successful fluoroscopic guided percutaneous vertebroplasty of
the L1 vertebral body without evidence of immediate
complication.

EXAM: CT guided lumbar spine biopsy
HISTORY: Right frontoparietal brain mass with multiple spinal
and paraspinal masses including right L3 and L5 pedicles.
Unknown primary malignancy. COMPARISON: Lumbar spine MRI
/2008
TECHNIQUE: Informed consent was obtained from the patient's wife
after discussion of the risks, benefits and alternatives of
the procedure. The patient was able to consent himself due to
altered mental status/confusion. The
risks discussed included were limited to complications of
conscious sedation including respiratory depression,
cardiovascular collapse, as well as risks of the procedure
including bleeding, infection, injury to nerves, vasculature, or
adjacent organs, non diagnosis. The patient's wife wished to proceed
and the signed informed consent was placed in the
chart.
The patient was evaluated for conscious sedation prior to the
procedure by Dr. . Oxygenation and vital signs were continuously
monitored. IV Versed and Fentanyl were administered by the
radiology nurse per order of and under the direct supervision
of Drs. .
Patient was placed prone on CT table. Axial 2.5mm sections were
obtained w/o contrast from L1 to L5. Skin over biopsy site
was marked with CT guidance. Skin was then prepped and draped in
sterile fashion. Adequate local anesthesia achieved with subcutaneous
1% lidocaine.
Under intermittent CT guidance, a 16 G x 9 cm Tenmo needle
biopsy system was advanced into the L3 right paraspinal
lesion and 2 core samples were obtained. A third pass was performed
with a 16 G x 6 cm needle and a third core sample was
obtained. Needle was removed and hemostasis easily achieved.
No immediate complications. Samples were submitted to
pathology for analysis.
I, Dr. was present throughout the
procedure.
FINDINGS: Pre biopsy images show a 2cm right
paraspinal soft tissue mass centered at the right L3 level with bony
involvement of the pedicle.
IMPRESSION: Successful CT guided biopsy of right L3 pedicle region
paraspinal mass without complication.

Preoperative embolization.
COMPARISON: Brain MRI, 3/12/07
PROCEDURE:
Informed consent was obtained by the patient and placed in patient chart. Patient was brought to the angiography suite and placed supine on the table. General anesthesia was administered. Right groin was draped and prepped in sterile fashion. Using seldinger technique an 18 G needle was used for vascular access in the right femoral artery with placement of a 4 Fr sheath.
Using a 4 Fr Vertebral catheter and .035 glidewire, diagnostic cerebral angiogram was performed with selective catheterization of the following vessels: Right CCA, Left vertebral, Left ICA and ECA. Using a .014 Excelsior microcatheter and Synchro wire, selective catheterization of the left posterior auricular and occipital arteries were performed and embolization performed using 250-350 micron PVA particles. Sheath was pulled in angiography suite with no complications and patient was transferred to PACU.
I, Dr. , Neurointerventional Attending, performed the entire procedure and was assisted by Dr. , Fellow Neuroradiology.
Findings:
Right CCA: There is normal filling and appearance of the ICA, ECA and distal branches. No aneurysms, AVMs or occlusion. Normal arterial, capillary and venous phases. At the junction of the left transverse sigmoid sinus there is focal narrowing which may be related to intracranial tumor compression. There is prominent nasal blush of unclear clinical significance.
Left ICA: There is normal filling and appearance of the ICA and distal branches including both A2 segments. There is a left fetal PCA origin. No aneurysms, AVMs or occlusion. There is normal arterial and venous phases with hypoperfusion on the capillary phase in the left parietal angular region which may be related to prior resection or infarct. As before, there is focal narrowing at the junction of the left transverse sigmoid sinus, but sinus remains patent. There is reflux into the ECA and branches.
Left ECA: There is normal filling of the ECA and branches. However, the superficial temporal artery is not visualized. There is tumor blush in the left temporal occipital region supplied by collateral branches off the STA, posterior auricular and occipital arteries. Left Vertebral: There is normal filling of the left vertebral artery, basilar and right PCA with reflux into the right vertebral artery. There is no filling of the left P1 segment due to fetal PCA origin. Normal arterial, venous and capillary phases.
Left CCA (post-embolization): There is mild persistent tumor blush along the anteroinferior left temporal occipital region via small branches off the occipital artery in proximity to the vertebral artery anastomosis; otherwise previous tumor blush supplied by the posterior auricular artery has been successfully embolized. Incidentally noted is a small plaque in the proximal left ICA just distal to the bifurcation, but with no significant stenoses.

SPINAL ANGIO
---------------------------------------------------------------
EXAM: Spinal angiogram with embolization
HISTORY: Metastatic squamous cell cancer with vertebral mets involving T7 and
T8; anticipating surgery; pre-operative embolization.
COMPARISON: MRI of the spine from February 12, 2008.
TECHNIQUE:
The risks and benefits of the procedure were discussed with the patient and written informed consent obtained. The patient was brought into the Angiography suite and general endotracheal anesthesia was provided by the Anesthesiology Service. Bilateral groins were prepped and draped in standard sterile fashion. The right common femoral artery was punctured using a single wall 18-gauge needle. A 5-French sheath was then placed using Seldinger technique.
A Chuang-II catheter was then utilized over a glide wire to select the following vessels: Left T6, T7, T8, and T9, and right T7, T8 and T9 intercostal arteries. Following this, the catheter was then used to select the right T7 artery.
At this point, a Renegade microcatheter was used with the help of a Synchro-200 guide wire to select the distal right T7 artery followed by embolization with PVA particles (250-350). Following this, a Tornado coil was deployed into the vessel. The right T8 intercostal artery was then similarly selected using the Renegade microcatheter and embolized using PVA particles followed by a single Tornado coil. The microcatheter was then used to select the left T7 artery followed by the deployment of a single Tornado coil. The catheter and sheath were then removed followed by manual compression and hemostasis. There were no immediate complications.
I, Dr., the attending radiologist, was personally present for the entire procedure.
FINDINGS:
LEFT T6 (AP): No vascular blush noted. No aneurysms or vascular malformations.
LEFT T7 (AP):In addition to prominent vascular tumor blush involving the T7 vertebral body, there is also supply to the posterior left spinal artery which fills cranially.
LEFT T8 (AP): Prominent tumor blush noted involving the T8 vertebral body. In addition there is supply to the artery of Adamkiewicz.
LEFT T9 (AP): No tumor blush noted. No aneurysms or vascular malformations.
RIGHT T9 (AP): No tumor blush, vascular malformations or aneurysms.
RIGHT T8 (AP): Faint tumor blush involving the T8 vertebral body noted. There is no evident spinal arterial supply.
RIGHT T7 (AP): Faint tumor blush noted involving the right T7 vertebral body. There is no evident spinal arterial supply.
IMPRESSION:
Endovascular embolization of the right T7 and T8 thoracic intercostal arteries with particles and coils, as well as embolization of the left T7 intercostal artery with a single coil. The left T8 intercostal artery is also associated with a prominent tumor blush; however, this vessel was noted to supply the artery of Adamkiewicz and was therefore not embolized.
Above findings were discussed with the Spine service immediately after the procedure.

VERTEBROPLASTY
--------------------------------------------------------
This patient is a participant of the INVEST study, a randomized study of vertebroplasty and as a result does not know if an actual vertebroplasty was performed. All persons reading this report should take care to prevent informing the patient about the information contained herein for one year following the date of this report.
HISTORY: L1 compression fracture.
EXAM: L1 vertebroplasty.
COMPARISON: MR lumbar spine 12/17/2007, plain radiographs of the
lumbar spine 12/17/2007.
TECHNIQUE: Written informed consent was obtained from the patient following a lengthy discussion of the benefits and risks of the procedure. All questions were answered. The consent was placed in the patient's chart.
Following this, the patient was brought to the angiography suite and placed prone upon the examination table. The patient was prepped and draped in the usual sterile fashion.
The L1 vertebral level was identified and targeted using fluoroscopy. The soft tissues above the left pedicle were anesthetized using lidocaine via a 25G needle and subsequently a 22G spinal needle. With a transpedicular approach, an 11 gauge needle was placed into the lateral aspect of the vertebral body under fluoroscopic guidance with position confirmed under lateral and frontal projections. This entire procedure was repeated with the patient's right L1 pedicle. Methymethacrylate was mixed and injected through both needles under direct fluoroscopic visualization, eventually opacifying the bilateral paracentral aspects of the vertebral body. Both needles were removed. The patient tolerated the procedure well with no immediate complications.
I, Dr., the attending Neuroradiologist, was present for all portions of the procedure.
FINDINGS: L1 vertebral compression fracture with approximately 30% vertebral height loss. 4 cc of methylmethacrylate mixed with barium was injected (2 cc through each pedicle). The distribution of the cement was observed under fluoroscopy. There is good bilateral distribution of cement. A small amount of cement extravasation is seen into the prevertebral soft tissues. Cement within the posterior aspect of the L1 vertebral body also approximates but does not appear to enter the central canal.
IMPRESSION:
1. Successful fluoroscopic guided percutaneous vertebroplasty of the L1 vertebral body without evidence of immediate complication.

HISTORY: Metastatic squamous cell cancer with vertebral mets involving
T7 and
T8; anticipating surgery; pre-operative embolization.
COMPARISON: MRI of the spine from February 12, 2008.
TECHNIQUE:
The risks and benefits of the procedure were discussed with
the patient and written informed consent obtained.
The patient was brought into the Angiography suite and
general endotracheal anesthesia was provided by the
Anesthesiology Service. Bilateral groins were prepped and
draped in standard sterile fashion. The right common femoral
artery was punctured using a single wall 18-gauge needle. A 5-French
sheath was then placed using Seldinger
technique.
A Chuang-II catheter was then utilized over a glide wire to
select the following vessels: Left T6, T7, T8, and T9, and
right T7, T8 and T9 intercostal arteries. Following this, the
catheter was then used to select the right T7 artery.
At this point, a Renegade microcatheter was used with the
help of a Synchro-200 guide wire to select the distal right
T7 artery followed by embolization with PVA particles
(250-350). Following this, a Tornado coil was
deployed into the vessel. The right T8 intercostal artery was
then similarly selected using the Renegade microcatheter and
embolized using PVA particles followed by a single Tornado
coil. The microcatheter was then used to select the left T7
artery followed by the deployment of a single Tornado coil. The
catheter and sheath were then removed followed by manual
compression and hemostasis. There were no immediate
complications.
I, Dr., the attending radiologist, was personally present for the
entire procedure.
FINDINGS:
LEFT T6 (AP): No vascular blush noted. No aneurysms or
vascular malformations.
LEFT T7 (AP):In addition to prominent vascular tumor blush

Adamkiewicz.
LEFT T9 (AP): No tumor blush noted. No aneurysms or vascular
malformations.
RIGHT T9 (AP): No tumor blush, vascular malformations or aneurysms.
RIGHT T8 (AP): Faint tumor blush involving the T8 vertebral body noted.
There is no evident spinal arterial supply.
RIGHT T7 (AP): Faint tumor blush noted involving the right T7 vertebral
body. There is no evident spinal arterial supply.
IMPRESSION:
Endovascular embolization of the right T7 and T8 thoracic
intercostal arteries with particles and coils, as well as
embolization of the left T7 intercostal artery with a single coil. The
left T8 intercostal artery is also associated with a
prominent tumor blush; however, this vessel was noted to
supply the artery of Adamkiewicz and was therefore not
embolized.
Above findings were discussed with the Spine service
immediately after the procedure.

VERTEBROPLASTY
--------------------------------------------------------
This patient is a participant of the INVEST study, a randomized study
of vertebroplasty and as a result does not know if an actual
vertebroplasty was performed. All persons reading this report should
take care to prevent informing the patient about the information
contained herein for one year following the date of this report.
HISTORY: L1 compression fracture.
EXAM: L1 vertebroplasty.
COMPARISON: MR lumbar spine 12/17/2007, plain radiographs of the
lumbar spine 12/17/2007.
TECHNIQUE: Written informed consent was obtained from the
patient following a lengthy discussion of the benefits and
risks of the procedure. All questions were answered. The
consent was placed in the patient's chart.
Following this, the patient was brought to the angiography
suite and placed prone upon the examination table. The
patient was prepped and draped in the usual sterile fashion.
The L1 vertebral level was identified and targeted using
fluoroscopy. The soft tissues above the left pedicle were
anesthetized using lidocaine via a 25G needle and
subsequently a 22G spinal needle. With a transpedicular
approach, an 11 gauge needle was placed into the lateral
aspect of the vertebral body under fluoroscopic guidance with
position confirmed under lateral and frontal projections.
This entire procedure was repeated with the patient's right
L1 pedicle. Methymethacrylate was mixed and injected through
both needles under direct fluoroscopic visualization,
eventually opacifying the bilateral paracentral aspects of
the vertebral body. Both needles were removed. The patient
tolerated the procedure well with no immediate
complications.
I, Dr., the attending Neuroradiologist, was present for all
portions of the procedure.
FINDINGS: L1 vertebral compression fracture with
approximately 30% vertebral height loss. 4 cc of
methylmethacrylate mixed with barium was injected (2 cc
through each pedicle). The distribution of the cement was
observed under fluoroscopy. There is good bilateral
distribution of cement. A small amount of cement
extravasation is seen into the prevertebral soft tissues.
Cement within the posterior aspect of the L1 vertebral body
also approximates but does not appear to enter the central canal.
IMPRESSION:
1. Successful fluoroscopic guided percutaneous vertebroplasty of
the L1 vertebral body without evidence of immediate
complication.

CT GUIDED SPINE BIOPSY
------------------------------------------------------------------
EXAM: CT guided lumbar spine biopsy
HISTORY: Right frontoparietal brain mass with multiple spinal
and paraspinal masses including right L3 and L5 pedicles.
Unknown primary malignancy. COMPARISON: Lumbar spine MRI
/2008
TECHNIQUE: Informed consent was obtained from the patient's wife
after discussion of the risks, benefits and alternatives of
the procedure. The patient was able to consent himself due to
altered mental status/confusion. The
risks discussed included were limited to complications of
conscious sedation including respiratory depression,
cardiovascular collapse, as well as risks of the procedure
including bleeding, infection, injury to nerves, vasculature, or
adjacent organs, non diagnosis. The patient's wife wished to proceed
and the signed informed consent was placed in the
chart.
The patient was evaluated for conscious sedation prior to the
procedure by Dr. . Oxygenation and vital signs were continuously
monitored. IV Versed and Fentanyl were administered by the
radiology nurse per order of and under the direct supervision
of Drs. .
Patient was placed prone on CT table. Axial 2.5mm sections were
obtained w/o contrast from L1 to L5. Skin over biopsy site
was marked with CT guidance. Skin was then prepped and draped in
sterile fashion. Adequate local anesthesia achieved with subcutaneous
1% lidocaine.
Under intermittent CT guidance, a 16 G x 9 cm Tenmo needle
biopsy system was advanced into the L3 right paraspinal
lesion and 2 core samples were obtained. A third pass was performed
with a 16 G x 6 cm needle and a third core sample was
obtained. Needle was removed and hemostasis easily achieved.
No immediate complications. Samples were submitted to
pathology for analysis.
I, Dr. was present throughout the
procedure.
FINDINGS: Pre biopsy images show a 2cm right
paraspinal soft tissue mass centered at the right L3 level with bony
involvement of the pedicle.

COMPARISON: MRI pituitary, 11/21/07 and CT head, 12/20/07
FINDINGS:
As before, patient is status post transphenoidal approach for residual
right pituitary macroadenoma. Postsurgical changes are present within
the nasal cavity, sphenoid and sella region related to recent
resection. There is subtle enhancing soft tissue convexity along the
right posterior aspect of the sella which likely represents
post-surgical changes and less likely residual disease. Expanded sella
with a fenestrated like appearance of the infundibulum remains
unchanged.
Scattered subcortical hyperintense FLAIR signal in the supratentorial
white matter remains unchanged. New area of hyperintense FLAIR signal
within the right midbrain is due to wrap around artifact from ear.

EXAM: Cerebral angiogram.
HISTORY: Cerebellar lesion, ataxia.
COPARISON: MR Brain 9/18/2007.
PROCEDURE:
Written informed consent was obtained from the patient after
a lengthy discussion of the risks and benefits of the
procedure. Risks discussed included but are not limited to
bleeding, pain, infection, vascular damage, allergic
reaction, and stroke. The patient was brought to the
angiography suite, placed in the supine position, and prepped
and draped in the usual fashion. Conscious sedation was
administered by the Radiology nursing staff.
The right common femoral artery was punctured using an 18
gauge single wall needle. Using Seldinger technique a 4
French sheath was inserted. Vessels, left CCA, right
vertebral, and right CCA were selectively catheterized using
a Glidewire and 4 French vertebral catheter. Selective
injections in multiple projections were performed in each of
these arteries. The patient tolerated the
procedure well without complication. The catheter
and sheath were removed and hemostasis was obtained with
manual compression. The patient left the angiography suite
neurologically unchanged.
I, Dr., the attending neuroradiologist, was present for the
entire procedure.
FINDINGS:
Right common carotid artery: (PA, Lateral). Normal terminal ICA. Normal
anterior and middle cerebral artery branches, with similarly
normal capillary and venous phases. No aneurysm or other
vascular anomaly. No vasospasm. No significant vascular
contribution to the posterior fossa.
Left common carotid artery: (PA, Lateral). Normal terminal ICA. Normal
anterior and middle cerebral artery branches, with similarly
normal capillary and venous phases. No aneurysm or other
vascular anomaly. No vasospasm. No significant vascular
contribution to the posterior fossa.
Right vertebral artery: (lateral, Townes ). A large, ovoid area of mild
vascular blush is present within the posterior fossa adjacent
to the tentorium correlating to the ring enhancing mass seen
on the MR examination. There is no enlarged vessel supplying
this area of blush. There is no arterial venous shunting
through this area. There is no significant contribution to
this area via collaterals from the anterior circulation.
Otherwise normal right vertebral and basilar artery. The
dural sinuses are grossly patent.
IMPRESSION:
1. Large, ovoid area of mild vascular blush within the
posterior fossa adjacent to the tentorium correlating with
the ring enhancing mass seen on the MR examination. No AV
shunting is detected. There is no enlarged vessel feeding

CEREBRAL ANGIO ñ TUMOR EMBO
--------------------------------------------------------------------
EXAM: Diagnostic cerebral angiogram and embolization
HISTORY: Recurrent gliosarcoma around left ear and neck.
Preoperative embolization.
COMPARISON: Brain MRI, 3/12/07
PROCEDURE:
Informed consent was obtained by the patient and placed in
patient chart. Patient was brought to the angiography suite
and placed supine on the table. General anesthesia was
administered. Right groin was draped and prepped in sterile
fashion. Using seldinger technique an 18 G needle was used
for vascular access in the right femoral artery with
placement of a 4 Fr sheath.
Using a 4 Fr Vertebral catheter and .035 glidewire,
diagnostic cerebral angiogram was performed with selective
catheterization of the following vessels: Right CCA, Left
vertebral, Left ICA and ECA. Using a .014 Excelsior
microcatheter and Synchro wire, selective catheterization of
the left posterior auricular and occipital arteries were
performed and embolization performed using 250-350 micron PVA
particles. Sheath was pulled in angiography suite
with no complications and patient was transferred to
PACU.
I, Dr. , Neurointerventional Attending, performed the entire
procedure and was assisted by Dr. , Fellow
Neuroradiology.
Findings:
Right CCA: There is normal filling and appearance of the ICA,
ECA and distal branches. No aneurysms, AVMs or occlusion.
Normal arterial, capillary and venous phases. At the junction
of the left transverse sigmoid sinus there is focal narrowing
which may be related to intracranial tumor compression. There
is prominent nasal blush of unclear clinical
significance.
Left ICA: There is normal filling and appearance of the ICA
and distal branches including both A2 segments. There is a
left fetal PCA origin. No aneurysms, AVMs or occlusion. There
is normal arterial and venous phases with hypoperfusion on
the capillary phase in the left parietal angular region which
may be related to prior resection or infarct. As before,
there is focal narrowing at the junction of the left
transverse sigmoid sinus, but sinus remains patent. There is
reflux into the ECA and branches.
Left ECA: There is normal filling of the ECA and branches.
However, the superficial temporal artery is not visualized.
There is tumor blush in the left temporal occipital region
supplied by collateral branches off the STA, posterior
auricular and occipital arteries. Left Vertebral:
There is normal filling of the left vertebral artery, basilar
and right PCA with reflux into the right vertebral artery.
There is no filling of the left P1 segment due to fetal PCA
origin. Normal arterial, venous and capillary
phases.
Left CCA (post-embolization): There is mild persistent tumor
blush along the anteroinferior left temporal occipital region
via small branches off the occipital artery in proximity to
the vertebral artery anastomosis; otherwise previous tumor
blush supplied by the posterior auricular artery has been
successfully embolized. Incidentally noted is a small plaque
in the proximal left ICA just distal to the bifurcation, but
with no significant stenoses.
IMPRESSION:
1. Successful tumor embolization via the left posterior
auricular and distal occipital artery branches with mild
persistent tumor blush along the anteroinferior temporal
occipital region from small branches off the occipital artery
in proximity to the vertebral artery anastomosis.
2. Focal narrowing at the junction of the left transverse
sigmoid sinus may be related to intracranial tumor
compression, but no sinus thrombosis.
3. Small plaque in the proximal left ICA just distal to
bifurcation with no significant stenoses.
4. Left fetal PCA origin.
Findings were discussed with Dr. Rostomily immediately after
the embolization.

SPINAL ANGIO
---------------------------------------------------------------
EXAM: Spinal angiogram with embolization
HISTORY: Metastatic squamous cell cancer with vertebral mets involving
T7 and
T8; anticipating surgery; pre-operative embolization.
COMPARISON: MRI of the spine from February 12, 2008.
TECHNIQUE:
The risks and benefits of the procedure were discussed with
the patient and written informed consent obtained.
The patient was brought into the Angiography suite and
general endotracheal anesthesia was provided by the
Anesthesiology Service. Bilateral groins were prepped and
draped in standard sterile fashion. The right common femoral
artery was punctured using a single wall 18-gauge needle. A 5-French
sheath was then placed using Seldinger
technique.
A Chuang-II catheter was then utilized over a glide wire to
select the following vessels: Left T6, T7, T8, and T9, and
right T7, T8 and T9 intercostal arteries. Following this, the
catheter was then used to select the right T7 artery.
At this point, a Renegade microcatheter was used with the
help of a Synchro-200 guide wire to select the distal right
T7 artery followed by embolization with PVA particles
(250-350). Following this, a Tornado coil was
deployed into the vessel. The right T8 intercostal artery was
then similarly selected using the Renegade microcatheter and
embolized using PVA particles followed by a single Tornado
coil. The microcatheter was then used to select the left T7
artery followed by the deployment of a single Tornado coil. The
catheter and sheath were then removed followed by manual
compression and hemostasis. There were no immediate
complications.
I, Dr., the attending radiologist, was personally present for the
entire procedure.
FINDINGS:
LEFT T6 (AP): No vascular blush noted. No aneurysms or
vascular malformations.
LEFT T7 (AP):In addition to prominent vascular tumor blush
involving the T7 vertebral body, there is also supply to the
posterior left spinal artery which fills cranially.
LEFT T8 (AP): Prominent tumor blush noted involving the T8
vertebral body. In addition there is supply to the artery of
Adamkiewicz.
LEFT T9 (AP): No tumor blush noted. No aneurysms or vascular
malformations.
RIGHT T9 (AP): No tumor blush, vascular malformations or aneurysms.
RIGHT T8 (AP): Faint tumor blush involving the T8 vertebral body noted.
There is no evident spinal arterial supply.
RIGHT T7 (AP): Faint tumor blush noted involving the right T7 vertebral
body. There is no evident spinal arterial supply.
IMPRESSION:
Endovascular embolization of the right T7 and T8 thoracic
intercostal arteries with particles and coils, as well as
embolization of the left T7 intercostal artery with a single coil. The
left T8 intercostal artery is also associated with a
prominent tumor blush; however, this vessel was noted to
supply the artery of Adamkiewicz and was therefore not
embolized.
Above findings were discussed with the Spine service
immediately after the procedure.

VERTEBROPLASTY
--------------------------------------------------------
This patient is a participant of the INVEST study, a randomized study
of vertebroplasty and as a result does not know if an actual
vertebroplasty was performed. All persons reading this report should
take care to prevent informing the patient about the information
contained herein for one year following the date of this report.
HISTORY: L1 compression fracture.
EXAM: L1 vertebroplasty.
COMPARISON: MR lumbar spine 12/17/2007, plain radiographs of the
lumbar spine 12/17/2007.
TECHNIQUE: Written informed consent was obtained from the
patient following a lengthy discussion of the benefits and
risks of the procedure. All questions were answered. The
consent was placed in the patient's chart.
Following this, the patient was brought to the angiography
suite and placed prone upon the examination table. The
patient was prepped and draped in the usual sterile fashion.
The L1 vertebral level was identified and targeted using
fluoroscopy. The soft tissues above the left pedicle were
anesthetized using lidocaine via a 25G needle and
subsequently a 22G spinal needle. With a transpedicular
approach, an 11 gauge needle was placed into the lateral
aspect of the vertebral body under fluoroscopic guidance with
position confirmed under lateral and frontal projections.
This entire procedure was repeated with the patient's right
L1 pedicle. Methymethacrylate was mixed and injected through
both needles under direct fluoroscopic visualization,
eventually opacifying the bilateral paracentral aspects of
the vertebral body. Both needles were removed. The patient
tolerated the procedure well with no immediate
complications.
I, Dr., the attending Neuroradiologist, was present for all
portions of the procedure.
FINDINGS: L1 vertebral compression fracture with
approximately 30% vertebral height loss. 4 cc of
methylmethacrylate mixed with barium was injected (2 cc
through each pedicle). The distribution of the cement was
observed under fluoroscopy. There is good bilateral
distribution of cement. A small amount of cement
extravasation is seen into the prevertebral soft tissues.
Cement within the posterior aspect of the L1 vertebral body
also approximates but does not appear to enter the central canal.
IMPRESSION:
1. Successful fluoroscopic guided percutaneous vertebroplasty of
the L1 vertebral body without evidence of immediate
complication.

TECHNIQUE: Informed consent was obtained from the patient's wife
after discussion of the risks, benefits and alternatives of
the procedure. The patient was able to consent himself due to
altered mental status/confusion. The
risks discussed included were limited to complications of
conscious sedation including respiratory depression,
cardiovascular collapse, as well as risks of the procedure
including bleeding, infection, injury to nerves, vasculature, or
adjacent organs, non diagnosis. The patient's wife wished to proceed
and the signed informed consent was placed in the
chart.
The patient was evaluated for conscious sedation prior to the
procedure by Dr. . Oxygenation and vital signs were continuously
monitored. IV Versed and Fentanyl were administered by the
radiology nurse per order of and under the direct supervision
of Drs. .
Patient was placed prone on CT table. Axial 2.5mm sections were
obtained w/o contrast from L1 to L5. Skin over biopsy site
was marked with CT guidance. Skin was then prepped and draped in
sterile fashion. Adequate local anesthesia achieved with subcutaneous
1% lidocaine.
Under intermittent CT guidance, a 16 G x 9 cm Tenmo needle
biopsy system was advanced into the L3 right paraspinal
lesion and 2 core samples were obtained. A third pass was performed
with a 16 G x 6 cm needle and a third core sample was
obtained. Needle was removed and hemostasis easily achieved.
No immediate complications. Samples were submitted to
pathology for analysis.
I, Dr. was present throughout the
procedure.
FINDINGS: Pre biopsy images show a 2cm right
paraspinal soft tissue mass centered at the right L3 level with bony
involvement of the pedicle.
IMPRESSION: Successful CT guided biopsy of right L3 pedicle region
