Name of the Patient : Abc Xyz Slmn / M / 37 yrs.
Referred by : Dr. Abc Xyzrchant.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

Developed a squint in the right eye on 00.00.00 with diminished vision and diplopia.

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, FLAIR and STIR coronal images.

OBSERVATION :

There is evidence of an intermediate signal intensity lesion on the T1 Weighted images in the prepontine cistern, slightly more to the right of the midline. This lesion appears relatively more hypointense on the proton and T2 Weighted images and appears close to the basilar artery.

There is no focal area of altered signal intensity within the brain parenchyma per se (hyperintense signal on the T2 Weighted images in the cerebral peduncles bilaterally most likely represents prominent perivascular spaces).

Both the lateral, third and the fourth ventricles are normal. There is no shift of the midline structures.










The visualized optic nerves on either side and the cavernous sinuses are unremarkable.

IMPRESSION :

Altered signal in the prepontine cistern, slightly more to the right of the midline as described is not specific for a single etiology. Basal exudates/meningeal pathology or subarachnoid haemorrhage may be considered in the differential diagnosis.

A contrast enhanced scan may be worthwhile.
