Name of the Patient : Abc Xyzth lmn / M / 55 yrs.
Referred by : Dr. Abc Xyzhtekar.
Examination : M.R.I. of the Brain with Contrast.
CLINICAL PROFILE :
C/O deafness of the right ear since 23 years.
Now C/O tinnitus and decreased hearing on the left side.
M.R.I of the brain was performed using the following parameters :
5 mm thick T1 Weighted, proton and T2 Weighted axial images.
MR cisternogram was also obtained.
3 mm thick T1 Weighted coronal images.
5 mm thick T1 Weighted sagittal images.
After administration of contrast, the following parameters were used :
3 mm thick T1 Weighted axial and coronal images.
There is thickening of the seventh and eighth cranial nerve complex on the left side (se/im 107/5, 106/6, 103/5, 102/5). This is slightly hyperintense to the normal nerve on the T1 Weighted images and appears hypointense on the proton and T2 Weighted images. There is effacement of the adjacent CSF space.
There is enhancement of the seventh and eighth cranial nerve on the left side on administration of contrast.
There is no area of abnormal enhancement within the brain parenchyma or the meninges.
Both the lateral, third and the fourth ventricles are normal. The basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.
The MRI features are suggestive of thickening of the seventh and eighth nerve complex on the left side with enhancement. These findings may be seen with,
1. An intracanalicular acoustic neurinoma.
2. Focal neuritis.
