Name of the Patient : Abc XyzKarlmn / M / 48 yrs.
Referred by : Dr. Abc Xyzngsarkar.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache with pain radiating to BLE (right more than left) since 1 year.

EXAMINATION :

M.R.I of the lumbo-sacral spine was performed using the following parameters :

5 mm thick T1 Weighted and T2 Weighted sagittal images.

5 mm thick T1 Weighted and T2 Weighted axial images.

OBSERVATION :

The lumbar intervertebral discs, more so at the L4-L5 level show loss of water content.

A large posterior disc extrusion, more to the right of the midline is seen to compress the thecal sac and narrow both neural foramina at the L4-L5 level. A disc portion is seen to lie within the anterior epidural space at the L5 vertebral level with resultant impingement of the traversing L5 nerve roots.

Mild facetal and ligamentum flavum hypertrophy is noted at the L4-L5 level.

The lumbar vertebral bodies reveal normal signal intensity. The rest of the facet joints and the visualized pre and paravertebral soft tissues are unremarkable.

The conus medullaris terminates at the L1 level and the thecal sac terminates at the S2 level.

The antero-posterior dimensions of the lumbar canal at the level of the intervertebral discs are as follows :

15.0 mm at L1-L2
16.0 mm at L2-L3
15.0 mm at L3-L4
8.0 mm at L4-L5
13.0 mm at L5-S1.

IMPRESSION :

The MRI features are suggestive of a large posterior disc extrusion, more to the right of the midline with canal stenosis at the L4-L5 level. A disc portion is seen to lie within the anterior epidural space at the L5 vertebral level with resultant impingement of the traversing L5 nerve roots.
