Name of the Patient : Abc Xyzm Y. Gailmn / M / 30 yrs.
Referred by : Dr. Abc Xyztal.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O gait ataxia, confused state, diminished vision and forgetfullness since 1 1/2 months.
Patient is HIV +ve.
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.
There are hypointense areas on the T1 Weighted images in cerebellar hemispheres bilaterally, both middle cerebellar peduncles, temporo-parieto-occipital lobes bilaterally and the frontal regions bilaterally. The subcortical U fibres, white matter and grey matter are involved. These are seen to turn hyperintense on the proton, T2 Weighted and Flair images. There is asymmetric fullness of the left lateral ventricle as compared to the right. The third ventricle is normal.
There is mild dilatation of the fourth ventricle with prominence of the cerebellar folia bilaterally.
The basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.
Incidental note is made of inflammatory changes in the left mastoid air cells and right maxilary sinus.
1. Altered signal in bilateral cerebellar hemispheres, both middle cerebellar peduncles, temporo-parieto-occipital lobes bilaterally and the frontal regions bilaterally may be seen with :
a. HIV encephalitis.
b. HIV related demyelination (less likely).
2. Cerebellar atrophy.
3. Left mastoiditis.
