Name of the Patient : Abc Xyzti Kanlmn / F / 47 yrs.
Referred by : Dr. Abc Xyzkia.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache with pain radiating to BLE since 3-4 years.

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 water content of all the lumbar intervertebral discs except the L4-L5 disc.

There is Grade I spondylolisthesis of the L4 over the L5 vertebra and the L5 over the S1 vertebra without obvious spondylolysis.

There is a postero-central and right postero-lateral disc herniation at the L5-S1 level with right neural foraminal narrowing and indentation on the traversing right S1 nerve root. Hypertrophic facetal arthropathy and canal stenosis is also noted at this level.

A small postero-central protruded disc is noted at the L4-L5 level. Hypertrophic facetal arthropathy and ligamentum flavum hypertrophy is also noted at this level, with a tight lumbar canal at that level.

Type II degenerative marrow changes are seen in the L3, L4 and L5 vertebrae adjacent to the intervertebral discs.



The rest of the lumbar vertebral bodies reveal normal signal intensity. 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 :

17.0 mm at L1-L2
15.0 mm at L2-L3
14.0 mm at L3-L4
9.0 mm at L4-L5
5.0 mm at L5-S1.

IMPRESSION :

1. Grade I spondylolisthesis of the L4 over the L5 vertebra and the L5 over the S1 vertebra without obvious spondylolysis.

2. A postero-central and right postero-lateral disc herniation at the L5-S1 level with right neural foraminal narrowing and indentation on the traversing right S1 nerve root. Hypertrophic facetal arthropathy and canal stenosis is also noted at this level.

3. A small postero-central protruded disc at the L4-L5 level with hypertrophic facetal arthropathy and ligamentum flavum hypertrophy and a tight lumbar canal at that level.
