Name of the Patient : Abc Xyzilal P. Limbalmn / M / 40 yrs.
Referred by : Dr. Abc Xyzchale.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
H/O right hemiparesis 1 month back.
Now C/O memory lapses.
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 coronal images.
There is a well-marginated hypointense lesion on the T1 Weighted images in the left lentiform nucleus extending into the left anterior capsular region, head of the left caudate nucleus and left corona radiata. This lesion appears hyperintense on the proton, T2 Weighted and FLAIR images. Resultant focal dilatation of the frontal horn and body of the left lateral ventricle is noted. Perilesional hyperintense signal on the T1 Weighted images which is isointense to normal white matter on the T2 Weighted images may represent paramagnetic substance deposition (less likely to represent haemoglobin breakdown products).
Hyperintense signal on the proton, T2 Weighted and FLAIR images is also noted in the left inferior frontal cortex, left high frontal cortex and in the right posterior parietal cortex.
The right lateral, third and 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 left frontal sinus.
The MRI features are suggestive of :
1. Altered signal in the left lentiform nucleus extending into the left anterior capsular region, head of the left caudate nucleus and left corona radiata represents an old infarct with gliotic/encephalomalacic changes.
2. Altered signal in the left inferior frontal cortex, left high frontal cortex and in the right posterior parietal cortex represents cortical infarcts.
