Name of the Patient : Abc Xyzaz Tlmn / M / 19 yrs.
Referred by : Dr. Abc Xyzvale.
Examination : Intracranial and Neck M.R.A.
CLINICAL PROFILE :
C/O left sided hemiparesis with slurred speech.
The brain was screened with 5 mm thick T2 Weighted axial images.
Intracranial MRA and MRV were performed with 3D TOF and 2D TOF sequences, respectively.
There is a bunch of curvilinear/punctate/serpigenous signal voids located within the right basal ganglia and these would most likely represent a cluster of vessels. Also seen are few hyperintense areas on the T2 Weighted images within this lesion and which may represent gliotic changes/recent haemorrhage.
The lesion is seen to compress upon the third ventricle and body of the right lateral ventricle. There is mild dilatation of the rest of the right lateral ventricle.
The fourth ventricle is unremarkable.
INTRACRANIAL MRA and MRV :
A cluster of vessels is seen in the region of the right basal ganglia. It is seen to be fed predominantly from the right posterior cerebral artery with a few feeders from the right middle cerebral artery.
The right posterior cerebral artery is prominent and tortuous. The basilar artery is prominent.
- 2 -
The lesion appears to be predominantly draining into the right internal cerebral vein. The Great vein of Galen and straight sinus are prominent.
The MRI features are suggestive of an arterio-venous malformation in the right basal ganglia with feeding vessels and draining vessels as described.
