Name of the Patient : Abc XyzNalmn / F / 40 yrs.
Referred by : Dr. Abc XyzV. Shah.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache with pain radiating to the LLE with paresthesias since 4 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.

OBSERVATION :

There is loss of normal lumbar lordosis.

There is a large postero-central disc extrusion, more to the left of the midline at the L5-S1 level with impingement of the traversing left S1 nerve root, mild indentation upon the traversing right S1 nerve root and mild compression upon the thecal sac.

A posterior disc herniation is seen at the L4-L5 level with mild neural foraminal narrowing and indentation upon the thecal sac. The L4-L5 facet joints show hypertrophic degenerative changes, right more than left.

There is a posterior disc bulge at the L3-L4 level. Bilateral far lateral (extraforaminal) disc bulges are seen at the L4-L5 and L5-S1 levels.

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 :

14.0 mm at L1-L2
14.0 mm at L2-L3
14.0 mm at L3-L4
11.0 mm at L4-L5
4.0 mm at L5-S1.

IMPRESSION :

1. A large postero-central disc extrusion, more to the left of the midline at the L5-S1 level with impingement of the traversing left S1 nerve root and mild indentation upon the traversing
right S1 nerve root.

2. A posterior disc herniation at the L4-L5 level.

3. Hypertrophic facetal arthropathy at the L4-L5 level, bilaterally (right more than left).

4. Canal stenosis at the L5-S1 level.
