Name of the Patient : Abc Xyzr Shlmn / M / 32 yrs.
Referred by : Dr. Abc Xyzichgar.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

H/O convulsion, vomiting, giddiness and ear perforation.
H/O ear clearing.

EXAMINATION :

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

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

6 mm thick FLAIR and Fast Scan (T2 *) coronal images.

5 mm thick T1 Weighted coronal and sagittal images.

A limited MR venogram was obtained.

OBSERVATION :

There are irregularly defined areas of hyperintensity on the FLAIR images within the right cerebellar hemisphere and both occipital lobes (left more than right). These are near isointense to grey matter on the T1 Weighted images.

There is fullness of the ventricular system.

Hyperintense signal on all the pulse sequences is noted within the transverse and sigmoid sinus on the left side extending into the left jugular vein. Patchy flow is seen within these sinuses on the MR venogram and this may represent thrombosis.

Irregularly defined areas of hypointensity on the T1 Weighted images are noted within the medial aspect of the left petrous bone (? inflammatory changes).


The pituitary gland shows a superior convex margin.

The basal cisternal spaces are unremarkable. There is no shift of the midline structures.

IMPRESSION :

The MRI features are suggestive of :

1. Areas of altered signal within the right cerebellar hemisphere and both occipital lobes (left more than right) are ischemic in etiology (most likely venous infarcts).

2. Probable thrombosis within the transverse and sigmoid sinus on the left side.

3. Fullness of the ventricular system.
