Name of the Patient : Abc Xyzi lmn / F / 43 yrs.
Referred by : Dr. Abc Xyzrankar.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to BLE with paresthesias since 00.00.00.
H/O fall prior to this.

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.

FEW IMAGES SHOW PATIENT MOTION.

OBSERVATION :

There is Grade I spondylolisthesis of the L5 vertebra over the S1 vertebra. Type II degenerative changes are seen within the L5 and S1 vertebral bodies adjacent to the L5-S1 intervertebral disc. The L3-L4, L4-L5 and L5-S1 intervertebral discs show loss of water content.

A posterior disc herniation is seen to indent the thecal sac and narrow both neural foramina with indentation upon the exiting L5 nerve roots at the L5-S1 level. The L5-S1 facet joints show hypertrophic degenerative changes, bilaterally.

There is a probable break of the pars interarticularis of the L5 vertebra bilaterally.

Small postero-central disc herniations are seen to indent the thecal sac at the L3-L4 and L4-L5 levels.

- 2 - Scan - 00005


The rest of 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 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 :

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

IMPRESSION :

The MRI features are suggestive of :

1. Grade I spondylolisthesis of the L5 vertebra over the S1 vertebra with probable spondylolysis of the L5 vertebra.

2. A posterior disc herniation with hypertrophic facetal arthropathy at the L5-S1 level.

3. Small postero-central disc herniations at the L3-L4 and L4-L5 levels.
