Name of the Patient : Abc Xyz Salmn / M / 46 yrs.
Referred by : Dr. Abc Xyzngsarkar.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to the LLE since 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 the L3-L4 and L4-L5 intervertebral discs.

There is inequality in the size of the laminae of the S1 vertebra. The left lamina being smaller than the right and is congenital in origin.

There is Grade I spondylolisthesis of the L5 vertebra over the S1 vertebra.

Minimal posterior disc bulges are noted at the L4-L5 and L5-S1 levels.

Slight facetal arthropathy is noted at the L5-S1 level, on the left.

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 D12-L1 level and the thecal sac terminates at the S2 level.
..2/.





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

16.0 mm at L1-L2
17.0 mm at L2-L3
18.0 mm at L3-L4
17.0 mm at L4-L5
16.0 mm at L5-S1.

IMPRESSION :

1. Congenital anomaly of the left lamina of the S1.

2. Slight facetal arthropathy at the L5-S1 level, on the left.

3. Grade I spondylolisthesis of the L5 over the S1 vertebra without spondylolysis.

4. Small posterior disc bulges at the L4-L5 and L5-S1 levels.
