Name of the Patient : Abc Xyzn Salgaolmn / M / 31 yrs.
Referred by : Dr. Abc Xyzdar.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O febrile convulsions at one year of age. Recurrent adverse reactions and emotional upsets every 6-7 months.
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.
3 mm thick T2 Weighted coronal images.
5 mm thick T1 Weighted sagittal images.
There is an extra-axial, CSF signal intensity lesion on all the pulse sequences in the left temporal region, which most likely represents an arachnoid cyst. There is mass effect with pressure on the underlying left temporal lobe.
The body and tail of the right hippocampal complex appears small in size and shows a hyperintense signal on the T2 Weighted images when compared to the left suggesting right sided mesial temporal sclerosis. Resultant mild focal dilatation of the temporal horn of the right lateral ventricle is noted.
The left lateral, 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.
A polyp is noted in the right maxillary antrum.
1. A well-marginated, extra-axial, CSF intensity lesion on all the pulse sequences in the left temporal region, most likely represents an arachnoid cyst.
2. Volume loss with increased signal of the right hippocampal complex suggests right sided mesial temporal sclerosis.
