Name of the Patient : Abc XyzCharntilmn / M / 48 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

H/O loss of vision bilaterally since April 0000.

EXAMINATION :

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 and T1 Weighted and STIR coronal images.

OBSERVATION :

The optic nerves are decreased in calibre bilaterally and show a hyperintense signal on the STIR images.

A small extra-axial lesion which appears to be arising from the inner table in the right temporal region is noted. It is hypointense on all the pulse sequences. It is seen to indent the adjacent right temporal lobe.

Both the 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.

IMPRESSION :

The MRI features are suggestive of :

1. Bilateral optic atrophy with altered signal (? the result of ischemia/neuritis).
2. A small extra-axial lesion in the right temporal region may represent an osteochondroma (? meningioma).
