Name of the Patient : Abc Xyzh Plmn / M / 19 yrs.
Referred by : Dr. Abc Xyzwant.
Examination : M.R.I. of the Dorsal Spine.

CLINICAL PROFILE :

Known C/O TBM for which a VP Shunt was placed in 0000 with excision of tuberculoma.
Was also operated upon the dorsal spine (D6 to D10 levels) for tuberculosis.
Patient has paresthesias in BLE.

EXAMINATION :

M.R.I of the dorsal spine was performed using the following parameters :

5 mm thick T1 Weighted and T2 Weighted sagittal images.

7 mm thick T1 Weighted and T2 Weighted axial images.

The brain was screened with 5 mm thick T2 Weighted axial images and 5 mm thick T1 Weighted sagittal images.

OBSERVATION :

There is evidence of laminectomy of the D7 to D11 vertebrae with post-operative changes in the posterior soft tissues over these levels.

The dorsal spinal cord over the D6 to D9 levels shows a hypointense signal on the T1 Weighted images which turn hyperintense on the T2 Weighted images and which may suggest gliotic/ischemic changes. The cord margins over these levels shows an irregular margin which may be the result of arachnoidits.
Scan-00008


The visualized dorsal vertebral bodies and intervertebral discs reveal normal signal intensity. The visualized pre and paravertebral soft tissues are unremarkable.

The conus medullaris terminates at the L1-L2 level.

On the screening the brain, there is a cystic lesion (isointense to CSF) within the left basal ganglia and left temporal lobe. There is perilesional edema with indentation upon the left cerebral peduncle. The exact etiology of this lesion is undetermined (? _trapped cyst/ventricle). A dedicated study of the brain with contrast may be worthwhile.

IMPRESSION :

The MRI features are suggestive of :

1. Post-operative status.

2. Altered cord signal with irregular cord margins over the D6 to D9 levels may represent gliotic/ischemic changes, probably the result of arachnoiditis.

3. The lesion in the brain needs to be further evaluated.
