Name of the Patient : Abc Xyzlmn / M / 60 yrs.
Referred by : Dr. Abc XyzB. Shah.
Examination : Intracranial and Neck M.R.A.
CLINICAL PROFILE :
C/O giddiness and gait ataxia.
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.
Prominent perivascular spaces are noted in the high fronto-parietal regions bilaterally.
Mild prominence of the cerebral cortical sulci and cerebellar folia is noted.
Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.
INTRACRANIAL MRA :
The right vertebral artery is not well visualized and is most likely hypoplastic.
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 :
There is a filling defect along the postero-lateral wall of the internal carotid artery on the left side just distal to the left common carotid bifurcation, suggestive of an atherosclerotic plaque.
The right vertebral artery in the neck is also is hypoplastic.
The common carotid arteries and their extracranial branches appear normal bilaterally.
1. Mild cerebral and cerebellar atrophy.
2. A filling defect along the postero-lateral wall of the internal carotid artery on the left side just distal to the left common carotid bifurcation suggestive of an atherosclerotic plaque.
