MALIGNANT TUMOR OF THE RIGHT TEMPORAL LOBE WITH INTRA-TUMOR HEMORRHAGE SLIPPED
TO THE POSTERIOR HORN.
Anamnesis
The patient an Iraqi citizen came to the clinic 28-June-2022
complaining of hallucination for 6 years. The
condition deteriorated 15-March-2022 with
condition of disorientation with headache and
sleepiness. MRI of the brain done 16-March-2022
showed a huge mass in the right temporo-parietal
lobes with intratumoral hemorrhage. The patient
is using Topamax 50 mg once daily, but still
complaining of fainting attacks. The patient is
a known hypertensive for 12 years in Lofral 5 mg
and Covarsyl 10/12.5 daily.
On examination, the patient complaining of
headache right side, weak right upper limb,
hypalgesia left leg below the knee, loss of
urination control, tremor right hand with deep
reflexes increased at the right side.
The patient was sent for thorough MRI
investigation, lab investigations and cardio
evaluation. MRI done 30-June-2022 under G.A.
showing the mass in the right temporal lobe
reaching and violating the right posterior horn
with residual of hematoma inside the tumor
cavity and the floor of the right posterior
horn. The tumor dimensions is around 5.6x3x3.3
cm in dimensions with minimal peritumoral edema.
The tumor is attached to the tentorium.
Spectroscopy suggesting high grade malignant
mass. There is right uncal herniation shifting
the right cerebral peduncle. There is widening
of the ventricular system with blood seen at the
bottom of the intratumoral cystic cavity and the
right posterior horn.
In semi lateral, with the
right ear up, curved incision done with the bone
flap reflected to the ear. The bone window was
extend3ed down to abut the floor of the middle
fossa. The dura was opened parallel to the
inferior edge of the bone window. The tumor was
attacked from the inferior part with massive
vascularity with massive venous loops. There was
hyperostosis of the floor of the middle fossa,
which was coagulated and waxed. The tumor was
followed up and resection was proceeded until
that part violating the posterior horn of the
right lateral ventricle. Several parts were sent
for biopsy. After strict hemostasis, the wound
was closed and the patient was sent for check
MRI. There is still a part of the tumor at the
upper most part of the resected tumor located
anteriorly. The wound was opened and that part
was removed. So as to avoid possible
postoperative bleeding a Surgicele was applied
to the resected tumor bed. Inspection of the
surround was uneventful and the pterion was
possible to see and running huge normal veins
were preserved at the edge of the tentorium. It
was impossible to see the vein of Labbe fro the
created dural flap. Routine closure. Attempt to
re-check MRI failed because the docking table of
the MRI machine was troubleshooting and the
Siemens engineer was fixing it. Smooth
postoperative recovery and the patent was sent
to the ICU.
FOLLOW UP
The patient showed slow improvement and
the final histologic result was of small cell
glioblastoma. The patient was advised to undergo
radiotherapy.
Comments
Spectroscopy confirming the malignant nature
of the tumor. The mass was full of abnormal huge veins
and the was a bony matrix to the tumor with rich feeders
from the bone of the floor of the right middle fossa.
Skyra MRI with all clinical applications in the run since 28-Novemeber-2013.
Inomed Riechert-Mundinger System, with three point
fixation is the most accurate system in the market. The microdrive and
its sensor gives feed back about the localization.
