Name of the Patient : Abc Xyz Humaid Abuhalmn / M / 50 yrs.
Referred by : Dr. Abc Xyz.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O right hemiparesis.
Known diabetic/hypertensive. On Rx.

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 and Fast Scan (T2 *) coronal images.

5 mm thick T1 Weighted sagittal images.

OBSERVATION :

There is an ill-defined hypointense area on the T1 Weighted images in the right fronto-temporal region which is seen to turn hyperintense on the proton, T2 Weighted and FLAIR images. There is dilatation of body of the right lateral ventricle and its
frontal horn and this lesion would represent an area of cystic encephalomalacia, the result of previous vascular insult. Resultant slight volume loss is also noted in this region.

Hyperintense areas are noted on the proton, T2 Weighted and FLAIR images within the lower pons (ponto-medullary junction), in the pons, anteriorly and to the left, parathird ventricular region,
posterior parietal periventricular white matter and the left fronto-parietal deep white matter. These are hypointense to normal white matter on the T1 Weighted images and are ischemic in etiology.

The left lateral, third and the fourth ventricles are normal. There is prominence of the cerebral cortical sulci bilaterally.
The basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.

IMPRESSION :

1. An area of cystic encephalomalacia in the right fronto-temporal region, the result of previous vascular insult.

2. Altered signal within the lower pons (ponto-medullary junction) in the pons, anteriorly and to the left, parathird ventricular region, posterior parietal periventricular
white matter and the left fronto-parietal deep white matter are ischemic in etiology.
