Name of the Patient : Abc Xyz lmn / M / 46 yrs.
Referred by : Dr. Abc Xyzhtekar.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

H/O surgery for a tumor (glial cell tumor) on 00.00.00. Lesion was a Grade III astrocytoma. Patient has received radiotherapy.
For follow-up.

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.

OBSERVATION :

There is evidence of a right frontal craniotomy.

There are fairly well-defined areas which are iso to hyperintense to CSF on all the pulse sequences within the right frontal lobe and would most likely represent cystic changes. Areas of hypointensity on the T1 Weighted images which turn hyperintense on the proton, T2 Weighted and FLAIR images are seen adjacent to these areas. Also seen is indentation upon and inferior displacement of the frontal horn and posterior body of the right lateral ventricle. There is a slight shift of the anterior falx to the left side.

The left lateral, third and the fourth 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 :

1. Post-operative status.

2. A mass lesion in the right frontal lobe as described. This most likely represents residual/recurrent lesion (? a few areas of cystic encephalomalacia may be the result of previous surgery.

A contrast enhanced scan would be worthwhile.
