Name of the Patient : Abc Xyz Shlmn / F / 15 yrs.
Referred by : Dr. Abc Xyzla.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
Known C/O craniopharyngioma in sellar region. V.P.Shunt was done on 00.00.00 and craniotomy for resection of craniopharyngioma on 00.00.00.
For follow up.
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 T1 Weighted and FLAIR coronal images.
5 mm thick T1 Weighted sagittal images.
There is a mixed signal intensity lesion in the suprasellar cistern on the T1 Weighted images which turns heterogeneously hyperintense on the proton, T2 Weighted and FLAIR images. This lesion measures approximately 2.8 x 2.7 cms. There is resultant splaying of the cerebral peduncle. A hypointense rim, more pronounced on the T2 Weighted images is noted around this lesion, which is probably a calcific rim.
An ill-defined, hypointense lesion is seen on the T1 Weighted images in the right lentiform nucleus which is slightly hyperintense to CSF on all the pulse sequences and represents post-operative changes.
A hyperintense signal is noted within the body of the third ventricle on the T1 Weighted images which is seen to turn hypointense on the proton and T2 Weighted images.

A right fronto-temporal craniotomy is noted with post-operative changes. A sliver of extradural collection is also noted at this site which is hyperintense on all the pulse sequences and would represent a post-operative hemorrhagic collection.
Subdural collection is seen fronto-temporal regions bilaterally.
A ventriculostomy tube tract is seen in the left frontal and right temporo-parietal region.
There is asymmetric fullness of the left lateral ventricle as compared to the right.
The fourth ventricle is normal. 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-operative/Post-shunt status.
2. Residual lesion in the suprasellar cistern measuring approximately 2.8 x 2.7 cms.
3. Altered signal within the body of the third ventricle follows the signal characteristics of fat and may represent a cholestrol containing fluid.
4. Subdural collection in the fronto-temporal regions bilaterally.
5. Post-operative, epidural collection in the right fronto-temporal region, with air pockets.
As compared to the previous MRI dated 00.00.00 (study no:00008), there is significant reduction in the cystic component of the lesion in the right temporal region. The suprasellar component has also reduced in size. The intra third ventricular component is largely unchanged.
