Name of the Patient : Abc Xyzt R. lmn / M / 3 1/2 yrs.
Referred by : Dr. Abc XyzV. Shah.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O weakness of the RLE.
H/O VP shunt done at the age of 2 months and spinal surgery 3 1/2 years back. (Exact details not available).
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.
The cerebellar hemispheres are seen to be wrapped around the brain stem. The fourth ventricle is slit-like. Cerebellar tonsillar ectopia is noted. Interdigitation of the sulcal spaces is noted more so in the parieto-occipital region in the midline due to ? fenestration of the falx. There appears to be stenogyria in the occipital lobes bilaterally.
The corpus callosum is well identified.
There is mild dilatation of the atrium and posterior body of the right lateral ventricle with an ill-defined, hyperintense signal in the periventricular white matter in that region and slight white matter loss. These changes may be the sequelae of previous shunt surgery. Both the lateral and third ventricles are otherwise collapsed. The tip of the shunt tube is not well defined.
- 2 - Scan-00007A
There is beaking of the tectal plate.
The basal cisternal spaces are unremarkable. No obvious vascular anomaly is identified on this study.
Susceptibility artifacts in the right temporo-parietal region is due to shunt tube reservoir.
The MRI features are suggestive of :
1. Post-shunt status.
2. Chiari II malformation.
3. Mild dilatation of the atrium and posterior body of the right lateral ventricle with altered signal in the periventricular white matter in that region and slight white matter loss may be the sequelae of previous shunt surgery.
