Name of the Patient : Abc Xyz Vishnupurlmn / M / 25 yrs.
Referred by : Dr. Abc Xyzmpat.
Examination : Intracranial and Neck M.R.A.
CLINICAL PROFILE :
H/O right sided hemiparesis in March 0000 from which patient has recovered completely.
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.
An area which is near isointense to CSF is seen in the left lentiform nucleus extending into the left corona radiata. Similar signal intensity changes are noted in the left temporo-parietal cortex and left insular cortex. Perilesional white matter hyperintense signal on the T2 Weighted images may represent gliosis. These would represent areas of cystic encephalomalacia.
There is slight fullness of the left lateral ventricle as compared to the right. The third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures.
INTRACRANIAL MRA :
The petrous, cavernous and supraclinoid segments of the internal carotid arteries bilaterally show normal signal and calibre. The visualized 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 :
Filling defects in the internal caortid artery at the level of the bifurcation bilaterally is artifactual (flow related artifacts).
The common carotid arteries and their extracranial branches appear normal bilaterally. There are no vessel wall irregularities or stenosis of the vessels noted.
Altered signal in the left lentiform nucleus, left corona radiata, left temporo-parietal cortex and in the left insular cortex would represent areas of cystic encephalomalacia.
No significant abnormality is detected on the intracranial and neck MRA on this study.
