Name of the Patient : Abc Xyzlmn / M / 29 yrs.
Referred by : Dr. Abc Xyzehta.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache with paresthesias in the RLE since 1 1/2 months and paresthesias in the LLE since 2-3 months.

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.

FEW IMAGES SHOW PATIENT MOTION.

OBSERVATION :

There is a large postero-central disc extrusion at the L4-L5 level with severe compression of the thecal sac and resultant canal stenosis. There is slight inferior migration of the disc with suggestion of mild inflammation of the traversing left L5 nerve root.

A small right postero-lateral disc herniation is seen at the L5-S1 level with mild indentation upon the traversing right S1 nerve root and mild right neural foraminal narrowing at this level.

The L4-L5 facet joints show mild degenerative changes.

The L4-L5 and L5-S1 intervertebral discs show loss of water content.

The lumbar vertebral bodies and the remaining intervertebral discs 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 S1 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
15.0 mm at L2-L3
15.0 mm at L3-L4
4.0 mm at L4-L5
11.0 mm at L5-S1.

IMPRESSION :

The MRI features are suggestive of :

1. A large postero-central disc extrusion at the L4-L5 level with resultant severe canal stenosis.

2. A small right postero-lateral disc herniation at the L5-S1 level with mild indentation upon the traversing right
S1 nerve root.
