Name of the Patient : Abc Xyz Abdul Relmn / F / 46 yrs.
Referred by : Dr. Abc Xyzlkaka.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O giddiness.
Past H/O surgery for a cerebellar astrocytoma in 0000 (No scans have been done previously).
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 evidence of a craniotomy in the left occipital region.
There is a well-defined, area which is isointense to CSF on all the pulse sequences within the left cerebellar hemisphere. Adjacent to this are areas of hypointensity on the T1 Weighted images which turn hyperintense on the proton, T2 Weighted and FLAIR images and would represent gliotic changes. This lesion in toto would represent an area of cystic encephalomalacia, most likely the result of previous surgery.
Hyperintense areas on the proton, T2 Weighted and FLAIR images are noted within the periatrial and frontal subcortical white matter bilaterally. These are iso to hypointense to normal white matter on the T1 Weighted images and are most likely ischemic in etiology.
There is mild prominence of the cerebral cortical sulci and cerebellar folia bilaterally.
Both the lateral, third and the fourth ventricles are normal. 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. Post-operative status.
2. An area of cystic encephalomalacia within the left cerebellar hemisphere is most likely the result of previous surgery. There is no obvious residual/recurrent lesion on this scan. If clinically indicated a contrast enhanced scan may be worthwhile.
3. Areas of altered signal within the periatrial and frontal subcortical white matter bilaterally are most likely ischemic in etiology.
