Name of the Patient : Abc Xyzaj lmn / M / 46 yrs.
Referred by : Dr. Abc Xyznna.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache with pain radiating to BLE (left more than right) with paresthesias since 0000.

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 INSPITE OF SEDATION.

OBSERVATION :

There is slight forward subluxation of the L5 vertebra over the S1 vertebra. There is a suspicion of spondylolysis of the L5 vertebra. Please correlate with plain radiographs.

A pseudoposterior disc bulge with a peridiscal osteophyte is seen at the L5-S1 level with mild bilateral neural foraminal narrowing. Bilateral far lateral (extraforaminal) disc bulges are seen at this level.

A small postero-central disc herniation is seen to indent the thecal sac at the L4-L5 level. A left far lateral (extraforaminal) disc herniation is seen to indent the extraforaminal portion of the exiting left L4 nerve root at the L4-L5 level.

A posterior disc bulge is noted at the L3-L4 level.

The L3-L4, L4-L5 and L5-S1 intervertebral discs show loss of water content.

The L3-L4 and L4-L5 facet joints bilaterally show mild degenerative changes.

Mild ligamentum flavum hypertrophy is seen at the L5 level.

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 :

16.0 mm at L1-L2

16.0 mm at L2-L3

15.0 mm at L3-L4

13.0 mm at L4-L5

18.0 mm at L5-S1.

2. A small postero-central disc herniation at the L4-L5 level.

3. A left far lateral (extraforaminal) disc herniation indenting the extraforaminal portion of the exiting left L4 nerve root at the L4-L5 level.

4. A posterior disc bulge at the L3-L4 level.

5. Facetal arthropathy at the L3-L4 and L4-L5 levels.
