Referred by : Dr. Abc Xyznghal.
Examination : Intracranial and Neck M.R.A.
CLINICAL PROFILE :
H/O giddiness and pain in the left half of the body with weakness on 00.00.00.
No complaints at present.
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 no focal area of altered signal intensity within the brain parenchyma.
Both the lateral, 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 paranasal sinuses.
INTRACRANIAL MRA :
There is hypoplasia of the left vertebral artery and the A1 segment of the left anterior cerebral artery.
The posterior communicating arteries are well-identified.
The petrous, cavernous and supraclinoid segments of the internal carotid arteries bilaterally show normal signal and calibre. The visualized right anterior cerebral, middle cerebral, basilar, right vertebral and posterior cerebral arteries also show normal signal, calibre and wall margins. No obvious aneurysm or vascular malformation is identified.
NECK MRA :
The left 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.
No significant abnormality is detected on the intracranial and neck MRA on this study.
