Name of the Patient : Abc Xyzi N. lmn / F / 66 yrs.
Referred by : Dr. Abc Xyzmpat.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O weakness of the LUE with tendency to fall towards one side.
Known diabetic/hyperintensive. On Rx.
H/O trauma +.
2 episodes of CVA earlier, recovered.

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.

OBSERVATION :

There is an ill-defined, hypointense area in the left temporo-parietal regions which is seen to follow CSF signal characteristics on all the pulse sequences. Hyperintense areas are seen at the periphery of this lesion on the proton, T2 Weighted and FLAIR images which would represent areas of gliosis. There is dilatation of the atrium and the occipital horn of the left lateral ventricle and this lesion would represent an area of cystic encephalomalacia. Few curvilinear hyperintense areas are seen within this lesion on the T1 Weighted images and turn hypointense on the T2 Weighted images and represent paramagnetic substance deposition.

A small hyperintense speck is seen in the right lateral aspect of the medulla, better appreciated on the FLAIR images (se/im 105/9). This is isointense to the white matter on the T1 Weighted images and would represent an area of infarction.


There is slight fullness of both the lateral ventricles. The third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures. The vertebro-basilary system is ectatic.

Incidental note is made of left maxillary polyp.

IMPRESSION :

The MRI features are suggestive of :

1. An area of cystic encephalomalacia in the left temporo-parietal regions as described.

2. A right lateral medullary infarct.
