Name of the Patient : Abc Xyz Andlmn / M / 52 yrs.
Referred by : Dr. Abc Xyzlkaka.
Examination : Intracranial and Neck M.R.A.
CLINICAL PROFILE :
C/O giddiness with gait ataxia since 3 months.
The brain was screened with 5 mm thick T2 Weighted axial images and 5 mm thick FLAIR coronal images.
Intracranial and neck MRA were performed with 3D TOF and 2D TOF sequences, respectively.
There is slight prominence of the right cerebellar folia, posteriorly, with a hyperintense signal on the T2 Weighted and FLAIR images in the cerebellar hemisphere in that region, which most likely is the sequelae of a previous vascular insult.
There is mild fullness of both the lateral and third ventricles. The fourth ventricle is normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.
INTRACRANIAL MRA :
The A1 segment of the right anterior cerebral artery and the right vertebral artery appears hypoplastic. The right posterior cerebral artery appears as a continuation of the right posterior communicating artery.
The petrous, cavernous and supraclinoid segments of the internal carotid arteries bilaterally show normal signal and calibre. The visualized left 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.
1. Altered signal in the right cerebellar hemisphere most likely represents an old infarct.
2. Hypoplastic A1 segment of the right anterior cerebral artery and the right vertebral artery.
3. No other significant abnormality is detected on the intracranial and neck MRA on this study.
