Name of the Patient : Abc Xyz Salmn / M / 26 yrs.
Referred by : Dr. Abc Xyzah.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

Known C/O pontine astrocytoma. Has received multiple cycles of radiotherapy.
Diplopia and ataxia still persist.

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.

5 mm thick T1 Weighted sagittal images.

3 mm thick T2 Weighted coronal images.

OBSERVATION :

There is an ill-defined, hypointense area in the pons, more so on the left side on the T1 Weighted images which is seen to turn hyperintense on the proton, T2 Weighted and FLAIR images. Inferiorly, the medulla is slightly involved. There is extension into the left middle cerebellar peduncle. Slight involvement of the left cerebellar hemisphere is also seen. There is mild indentation upon the anterior and left lateral aspect of the fourth ventricle.

The third and both the lateral ventricles are normal. The basal cisternal spaces are unremarkable. No obvious vascular anomaly is identified on this study.

IMPRESSION :

The MRI features are suggestive of an ill-defined mass lesion (known C/O astrocytoma) in the pons with extensions as described.

As compared to the previous MRI (study no:00008) dated 00.00.00, there is marked decrease in the size of the lesion. The ventricles have also decreased in size.
