Name of the Patient : Abc XyzTrilmn / M / 45 yrs.
Referred by : Dr. Abc Xyzrikh.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

H/O left radical mastoidectomy on 00.00.00 with loss of hearing and discharge from the left ear.
Now C/O discharge from the right ear with decreased hearing on the right side and headaches.

EXAMINATION :

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.
3 mm thick T1 Weighted coronal images.
MR Cisternogram was obtained.
5 mm thick T1 Weighted sagittal images.

PATIENT REFUSED CONTRAST ADMINISTRATION.

OBSERVATION :

Intermediate signal intensity lesion is seen in the mastoid air cells bilaterally on the T1 Weighted images which is seen to turn hyperintense on the proton, T2 Weighted and FLAIR images. There is suspicious erosion of the petrous temporal bone, which is better appreciated on the CT scan.

The seventh and eighth cranial nerve complex on either side is unremarkable. There is no intracranial extension of the disease process on this non-contrast study.

There is no focal area of altered signal intensity in the brain parenchyma.
Scan-00008



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.

IMPRESSION :

Inflammatory changes in both mastoid air cells.

Normal study of the brain.
