Name of the Patient : Abc Xyzbhai Sulmn / M / 54 yrs.
Referred by : Dr. Abc XyzJain.
Examination : Intracranial and Neck M.R.A.
CLINICAL PROFILE :
H/O loss of vision of the right eye in 0000.
C/O giddiness with gait ataxia since 00.00.00.
EXAMINATION :
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.
OBSERVATION :
There are small bright foci on the T2 Weighted images in the right cerebellar hemisphere, inferiorly and in the right middle cerebral peduncle. These lesions most likely represent subacute ischemic changes (on correlating with previous CT Scan dated 00.00.00).
Ill-defined, hyperintense signal on the T2 Weighted images in the right posterior parietal parafalcine region, also most likely represent a sequelae of previous vascular insult.
Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is slight prominence of the cerebellar folia bilaterally. There is no shift of the midline structures.
Mucosal thickening is noted in the maxillary sinuses bilaterally.
INTRACRANIAL MRA :
The right vertebral artery appears hypointense when compared to the left.
>
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 posterior cerebral arteries also show normal signal, calibre and wall margins. No obvious aneurysm or vascular malformation is identified.
NECK MRA :
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.
IMPRESSION :
1. Altered signal in the right cerebellar hemisphere, inferiorly, in the right middle cerebral peduncle and in the right posterior parietal parafalcine region most likely represent subacute ischemic lesions.
2. Hypoplastic right vertebral artery.
No other significant abnormality is detected on the MRA on this study.
