Name of the Patient : Abc Xyz Khlmn / M / 50 yrs.
Referred by : Dr. Abc Xyzni.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to BLE with paresthesias since 6 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 mild retroplacement of the L5 vertebra over the S1 vertebra.

The lumbar intervertebral discs show loss of water content.

The L5-S1 intervertebral disc appears reduced in height.

A large postero-central disc herniation is seen to indent the thecal sac at the L2-L3 level. There is facetal and ligamentum flavum hypertrophy at this level with canal stenosis.

A small posterior disc herniation is seen to indent the thecal sac and narrow both neural foramina at the L5-S1 level.

A small posterior disc bulge is seen to indent the thecal sac and narrow both neural foramina at the L4-L5 level.

Small postero-central and left postero-lateral disc herniations are seen to indent the thecal sac and narrow the left neural foramen, respectively at the L3-L4 level.

>

There is a left paracentral disc protrusion indenting the ventral aspect of the thecal sac at the L1-L2 level.

Bilateral far lateral (extraforaminal) disc herniations are noted at the L2-L3, L3-L4, L4-L5 and L5-S1 levels.

The remaining lumbar facet joints show degenerative changes. Mild ligamentum flavum hypertrophy is noted in the lumbar region.

The pedicles of the lumbar vertebrae appear to be congenitally short in their antero-posterior dimensions.

Multipe Schmorls nodes are noted in the lumbar region. Focal fatty changes/Type II degenerative changes are seen within the S1 and lumbar vertebral bodies.

Small anterior disc herniations are seen in the lumbar region.

A cortical renal cyst is noted on the right side.

The visualized pre and paravertebral soft tissues are unremarkable.

The conus medullaris terminates at the L1-L2 level and the thecal sac terminates at the S1-S2 level.

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

11.0 mm at L1-L2
9.0 mm at L2-L3
12.0 mm at L3-L4
12.0 mm at L4-L5
12.0 mm at L5-S1.

IMPRESSION :

The MRI features are suggestive of :

1. A large postero-central disc herniation at the L2-L3 level with canal stenosis.

2. A small posterior disc herniation at the L5-S1 level.

3. A small posterior disc bulge at the L4-L5 level with a tight canal.

4. Small postero-central and left postero-lateral disc herniations at the L3-L4 level with a tight canal.

5. A left paracentral disc protrusion at the L1-L2 level.

6. Facetal arthropathy and mild ligamentum flavum hypertrophy in the lumbar region.

7. Congenitally short pedicles of the lumbar vertebrae in their antero-posterior dimensions.
