Name of the Patient : Abc Xyzce Mendlmn / M / 41 yrs.
Referred by : Dr. Abc Xyzhijwala.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to the RLE.

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 slight forward translation of the L5 over the S1 vertebral body with probable lysis of the L5 vertebra on the left side. Correlation with plain radiographs would be worthwhile.

A pseudo-posterior disc bulge is seen at the L5-S1 level.

Small postero-central disc herniation is seen at the L3-L4 level and a posterior disc bulge is noted at the L4-L5 level. The L3-L4, 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 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.
R>
The antero-posterior dimensions of the lumbar canal at the level of the intervertebral discs are as follows :

14.0 mm at L1-L2
13.0 mm at L2-L3
13.0 mm at L3-L4
13.0 mm at L4-L5
15.0 mm at L5-S1.

IMPRESSION :

The MRI features are suggestive of :

1. Slight forward translation of the L5 over the S1 vertebral body with probable lysis of the L5 vertebra on the left side. Correlation with plain radiographs would be worthwhile.

2. A pseudo-posterior disc bulge at the L5-S1 level.

3. Small postero-central disc herniation at the L3-L4 level and a posterior disc bulge at the L4-L5 level.
