Name of the Patient : Abc Xyz Jlmn / M / 42 yrs.
Referred by : Dr. Abc Xyzmpat.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to the LLE since 15 days.

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 intervertebral disc.

Small posterior disc bulges are noted at the L3-L4 and L4-L5 levels with slight bilateral neural foraminal narrowing at the L4-L5 level. An anterior disc herniation is seen at the L3-L4 level.

Small posterior peridiscal osteophytes are noted at the D12-L1 and L3-L4 levels.

An ill-defined hypointense signal on all the pulse sequences is noted in the ala of the sacrum on the left adjacent to the left L5-S1 facet joint. This may represent sclerosis. There is suspicious lysis of the L5 vertebra on the left side.

Focal hypointense lesions on all the pulse sequences in the L3 and L4 vertebral bodies most likely represent bone islands.

The pedicles of the lumbar vertebrae are congenitally short in their antero-posterior dimensions.


The articular facets at L3-L4, L4-L5 and L5-S1 levels appear slightly hypertrophied.

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 L1-L2 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 :

20.0 mm at L1-L2

16.0 mm at L2-L3

16.0 mm at L3-L4

12.0 mm at L4-L5

13.0 mm at L5-S1.

IMPRESSION :

1. Small posterior disc bulges at the L3-L4 and L4-L5 levels with slight bilateral neural foraminal narrowing at the L4-L5 level.

2. Small posterior peridiscal osteophytes at the D12-L1 and L3-L4 levels.

3. Altered signal in the ala of the sacrum on the left, adjacent to the left L5-S1 facet joint may represent sclerosis. Suspicious lysis of the L5 vertebra on the left side. Please correlate with plain radiographs.

4. Bone islands in the L3 and L4 vertebral bodies.

5. Congenitally short pedicles of the lumbar vertebrae in their antero-posterior dimensions.

6. Slight facetal hypertrophy at the L3-L4, L4-L5 and L5-S1 levels.
