Name of the Patient : Abc Xyz Vishnupurlmn / M / 25 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of brain.
CLINICAL PROFILE :
H/O sudden onset of right sided hemiparesis on 00.00.00 (has recovered).
M.R.I of the brain was performed using the following parameters :
5 mm thick T1 Weighted, proton and T2 Weighted axial images.
5 mm thick FLAIR and Fast Scan (T2 *) coronal images.
There is a well-marginated, hypointense lesion on the T1 Weighted images in the lentiform nucleus, extending into the left corona radiata. This lesion is near isointense to CSF on all the pulse sequences and represents an area of cystic encephalomalacia, the sequelae of previous vascular insult. 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 and FLAIR images may represent gliosis.
Mild fullness of the left lateral ventricle is noted 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. No obvious vascular anomaly is identified on this study.
Inflammatory changes are noted in the ethmoidal air cells and maxillary sinuses bilaterally.
Altered signal in the left lentiform nucleus, left corona radiata, left temporo-parietal cortex and in the left insular cortex represents cystic encephalomalacia, the sequelae of previous vascular insult.
As compared to the previous MRI (scan no. 00005/57) dated 00.00.00, the previously identified ischemic lesions have evolved to areas of cystic encephalomalacia.
