Name of the Patient : Abc Xyz lmn / F / 40 yrs.
Referred by : Dr. Abc Xyzrankar.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to the LLE with numbness.
Old H/O trauma.

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 Grade I spondylolisthesis of the L4 over the L5 vertebrae with probable spondylolysis at L4. Correlation with plain X-rays would be worthwhile.

A pseudoposterior disc herniation is seen at the L4-L5 level with anterior indentation of the thecal sac and bilateral neural foraminal narrowing. The L4-L5 facet joints show hypertrophic degenerative changes. Ligamentum flavum hypertrophy is also noted at this level with resultant canal stenosis.

A small, postero-central and right postero-lateral disc herniations with peridiscal osteophytes is seen at the L3-L4 level with mild neural foraminal narrowing. The L3-L4 facet joints show hypertrophic degenerative changes.

Ligamentum flavum hypertrophy is noted over the L2-L3 to L4-L5 levels.
Scan-00001


The L5-S1 facet joints show hypertrophic degenerative changes (left more than right).

The lumbar intervertebral discs except for the L5-S1 disc show loss of water content.

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 :

16.0 mm at L1-L2
15.0 mm at L2-L3
13.0 mm at L3-L4
12.0 mm at L4-L5
10.0 mm at L5-S1.

IMPRESSION :

1. Grade I spondylolisthesis of the L4 over the L5 vertebra with probable spondylolysis at L4. Correlation with plain X-rays would be worthwhile.

2. A pseudoposterior disc herniation at the L4-L5 level with hypertrophic facetal arthropathy and ligamentum flavum hypertrophy and resultant canal stenosis.

3. A small, postero-central and right postero-lateral disc herniations with peridiscal osteophyte at the L3-L4 level with hypertrophic facetal arthropathy at this level.

4. Hypertrophic facetal arthropathy at the L5-S1 level (left more than right).
