Name of the Patient : Abc Xyzhlmn / M / 35 yrs.
Referred by : Dr. Abc Xyzmat.
Examination : Intracranial and Neck M.R.A.
CLINICAL PROFILE :
C/O paresthesias on the left side of the body.
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 :
Few small bright foci are seen on the T2 Weighted images within the white matter in the fronto-parietal lobes bilaterally and these are most likely ischemic in etiology.
There is mild prominence of the cerebral cortical sulci bilaterally.
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 A1 segment of the right anterior cerebral artery is hypoplastic.
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, 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 appears to be arising directly from the aortic arch.
The common carotid arteries and their extracranial branches appear normal bilaterally. There are no vessel wall irregularities or stenosis of the vessels noted.
IMPRESSION :
The MRA features are suggestive of :
1. Few foci of altered signal intensity within the white matter in the fronto-parietal lobes bilaterally are most likely ischemic in etiology.
2. The left vertebral artery is seen to arise directly from the aortic arch.
