Referred by : Dr. Abc Xyzdi / Dr. Abc Xyzthan.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to the LLE with paresthesias since 1 month.

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 :

There is a posterior disc herniation at the L4-L5 level with anterior indentation of the thecal sac and bilateral neural foraminal narrowing, left more than right. There is mild indentation upon the foraminal portion of the exiting left L4 nerve root. Ligamentum flavum and facetal hypertrophy is also noted at this level.

A posterior disc bulge is seen at the L3-L4 level. The L3-L4 facet joints show mild degenerative changes.

The lumbar intervertebral discs show loss of water content.

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 D12-L1 level and the thecal sac terminates at the S1 level.

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

16.0 mm at L1-L2
14.0 mm at L2-L3
14.0 mm at L3-L4
13.0 mm at L4-L5
12.0 mm at L5-S1.

IMPRESSION :

A posterior disc herniation at the L4-L5 level with ligamentum flavum and facetal hypertrophy with a resultant tight canal at this level.
