Name of the Patient : Abc Xyzath Mhlmn / M / 29 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O seizures since 2 years and weakness of the RUE since childhood.

EXAMINATION :

M.R.I of the brain was performed using the following parameters :

5 mm thick T1 Weighted, proton and T2 Weighted axial images.

3 mm thick T1 Weighted and T2 Weighted coronal images.

OBSERVATION :

The left cerebral hemisphere shows loss of volume when compared to the right. There is resultant prominence of the cerebral cortical sulci of the left cerebral hemisphere, mild dilatation of the left lateral ventricle and slight hyperpneumatization of the left frontal sinus and the orbital plate of the left frontal bone.

The left hippocampal complex appears smaller in volume when compared to the right with hyperintense signal on the T2 Weighted images suggesting left hippocampal sclerosis.

There is a small, well-marginated CSF signal intensity extra-axial lesion on all the pulse sequences in the left cerebello-pontine angle cistern. This lesion most likely represents an arachnoid cyst.







The right lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is mild bulge of the midline to the left. No obvious vascular anomaly is identified on this study.

IMPRESSION :

1. Left sided cerebral hemiatrophy.

2. Reduction in the left hippocampal volume with altered signal suggests left hippocampal sclerosis.

3. A small, CSF signal intensity extra-axial lesion in the
left cerebello-pontine angle cistern most likely represents an arachnoid cyst.
