Name of the Patient : Abc Xyzi Chikhalmn / M / 70 yrs.
Referred by : Dr. Abc Xyzgaonkar.
Examination : Intracranial and Neck M.R.A.
CLINICAL PROFILE :
C/O right sided hemiparesis since 4-5 days with giddiness.
H/O fever prior to this.
The brain was screened with 5 mm thick T2 Weighted axial images.
Intracranial and neck MRA were performed with 3D TOF and 2D TOF sequences, respectively.
There is an ill-defined, hyperintense signal on the T2 Weighted images in the midbrain to the left of the midline. This most likely represent an ischemic lesion.
There is mild dilatation of both the lateral ventricles. The third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.
Inflammatory changes are noted in the right maxillary antrum.
INTRACRANIAL MRA :
The right vertebral artery is hypoplastic.
Slight irregularity and narrowing of the P2 segment of the left posterior cerebral artery is noted.
The petrous, cavernous and supraclinoid segments of the internal carotid arteries bilaterally show normal signal and calibre. The visualized anterior cerebral, middle cerebral, basilar, left vertebral and right posterior cerebral arteries also show normal signal, calibre and wall margins. No obvious aneurysm or vascular malformation is identified.
NECK MRA :
Motion artifacts are noted.
The right vertebral artery in the neck also appears hypoplastic.
The common carotid arteries and their extracranial branches appear normal bilaterally. There are no vessel wall irregularities or stenosis of the vessels noted.
1. Altered signal in the midbrain to the left of the midline most likely represent an ischemic lesion.
2. Slight irregularity and narrowing of the P2 segment of the left posterior cerebral artery.
3. Hypoplastic right vertebral artery.
