Name of the Patient : Abc Xyzn M. Jaitalmn / M / 13 yrs.
Referred by : Dr. Abc Xyzhiri.
Examination : M.R.I. of the Sella & Perisellar region.
CLINICAL PROFILE :
K/C/O Dandywalker syndrome with VP Shunt done in June 0000.
Again operated in March 0000 and June 0000 with bifid scrotum.
C/O headaches and short stature.
M.R.I of the sella and perisellar region was performed using the following parameters :
3 mm thick T1 Weighted and T2 Weighted coronal images.
3 mm thick T1 Weighted and T2 Weighted sagittal images.
The brain was screened with 5 mm thick T2 Weighted axial images.
There is a large cyst in the posterior fossa following CSF signal intensity characteristics on all the pulse seqeunces. This cyst is seen to be in communication with the posterior aspect of the fourth ventricle. There is slight hypoplasia of the cerebellar hemispheres, bilaterally and the inferior cerebellar vermis.
Slight thinning of the posterior part of the body of the corpus callosum is noted.
A ventriculostomy tube is seen to traverse through the right temporo-parietal region and the tip is seen to lie in the body of the right lateral ventricle. Susceptibility artifacts are noted in the right posterior temporo-parietal region.
The pituitary gland is normal in its size, contour and location and reveals normal signal intensity. The posterior pituitary gland reveals normal hyperintense signal on the T1 Weighted images. The pituitary stalk is in the midline. The hypothalamus is unremarkable.
There is no focal area of altered signal intensity in the brain parenchyma.
Both the lateral and the third ventricles are collapsed. The rest of the basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.
1. Post-shunt status.
2. Dandywalker variant features.
3. Normal study of the sella and perisellar region.
