Name of the Patient : Abc Xyz S. Tendulmn / F / 42 yrs.
Referred by : Dr. Abc Xyzwant.
Examination : M.R.I. of the Brain.
CLINICAL PROFILE :
C/O numbness over the left side of the face with tinnitus, diminished vision and loss of taste.
H/O VP Shunt done on 00.00.0000.
M.R.I of the brain was performed using the following parameters :
5 mm thick T1 Weighted, proton and T2 Weighted axial images.
3 mm thick T1 Weighted coronal images.
5 mm thick T1 Weighted sagittal images.
MR Cisternogram was obtained in the coronal plane.
There is seen a fairly large, approximately 3.2 x 2.9 x 3.2 cms sized well-defined extra-axial mass lesion in the left cerebello-pontine angle cistern, with its broad base towards the left petrous temporal bone. This lesion is of intermediate signal on the T1 Weighted images and appears relatively hypointense on the T2 Weighted images with peripheral hypointense signal. A CSF cleft is noted around this lesion. There is resultant compression of the left middle cerebellar peduncle and the fourth ventricle which is displaced slightly to the right of the midline. Probable extension of the lesion along the proximal left seventh and eighth cranial nerve complex is noted.
Both the lateral and the third ventricles are collapsed with a shunt tube noted in the body of the left lateral ventricle. Right posterior parietal and right high frontal burr holes are noted.
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. A fairly large, approximately 3.2 x 2.9 x 3.2 cms sized extra-axial mass lesion in the left cerebello-pontine angle cistern, with probable extension along the proximal seventh and eighth cranial nerve complex most likely represent an acoustic neurinoma.
As compared to the previous CT Scan dated 00.00.0000, the patient is now post-shunt status with decrease in the size of the lateral ventricles. There is no significant change in the size of the lesion.
