Name of the Patient : Abc Xyzan Salmn / M / 45 yrs.
Referred by : Dr. Abc Xyzchale.
Examination : M.R.I. of the Brain.

CLINICAL PROFILE :

C/O tinnitus on the right side since 7-8 years with hearing loss (on right side) since 5-6 months.
C/O giddiness, speech disturbances and gait imbalance since 8-10 days.

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 and MR Cisternogram in the coronal plane through the seventh and eighth cranial nerve complex.

OBSERVATION :

There is seen an approximately, 7.0 mm diameter sized, well-marginated, hypointense lesion, best appreciated on the proton and T2 Weighted images in the left cerebellar hemisphere, inferiorly and peripherally. This lesion is not well-identified on the T1 Weighted images. Minimal perilesional hyperintense signal is seen on the proton, T2 Weighted and FLAIR images. There is prominence of the cerebellar folia in that region.

The seventh and eighth cranial nerve complex on either side are unremarkable.

Prominent perivascular spaces are noted in the cerebral hemispheres bilaterally.


Both the lateral, third and the fourth ventricles are normal. There is slight prominence of the cerebral cortical sulci and cerebellar folia bilaterally. The basal cisternal spaces are unremarkable. There is no shift of the midline structures. No obvious vascular anomaly is identified on this study.

Pansinusitis is noted with inflammatory changes in the right middle ear.

IMPRESSION :

1. An approximately, 7.0 mm diameter sized, well-marginated, lesion, in the left cerebellar hemisphere, inferiorly and peripherally with signal characteristics as described most likely represents a calcific density, ? a calcified granuloma. Perilesional altered signal may represent gliotic changes. Slight volume loss is also noted at the site of the lesion.

2. Pansinusitis.

3. Inflammatory changes in the right middle ear.
