Name of the Patient : Abc Xyz Anlmn / M / 32 yrs.
Referred by : Dr. Abc Xyzgaonkar.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O paresthesias in BLE with retention of urine since 5-6 days.
H/O fever +.
Previous MRI of spine s/o myelitis/demyelination at D1 to D11-D12 and at the L1, C6 and C2 to C4 levels.

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 FLAIR sagittal images.

3 mm thick STIR coronal images through the optic nerves.

OBSERVATION :

There are areas of hyperintensity on the proton, T2 Weighted and FLAIR images within the right middle cerebellar peduncle and at the ponto-mesencephalic junction, more to the right of the midline. These are hypointense to white matter on the T1 Weighted images (scans 103.5 - 103.7, 106.13 - 106.15, 102.5 - 102.7).

There is mild fullness of both the lateral ventricles. There is mild prominence of the cerebral cortical sulci and cerebellar folia bilaterally.

There is a suggestion of slow flow within the sigmoid and transverse sinuses on the left side.

The visualized optic nerves bilaterally show normal signal intensity on this STIR images.


The 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 altered signal within the right middle cerebellar peduncle and at the ponto-mesencephalic junction, more to the right of the midline and is not specific for a single diagnosis.

The possibilities of these being plaques of demyelination should be considered strongly (especially in view of the cord signal study no:00009 dated 00.00.00).
