Name of the Patient : Abc Xyzlmn / M / 20 yrs.
Referred by : Dr. Abc Xyzdkarni.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to the RLE with paresthesias.

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 :

The L5 vertebra is as marked on the film.

There is a probable break of the pars interarticularis of the L5 vertebra bilaterally, with slight forward subluxation of the L5 over the S1 vertebra.

A small, postero-central disc herniation with peridiscal osteophytes, more to the right of the midline is seen to indent the traversing right L5 nerve root at the L4-L5 level. This intervertebral disc shows slight decrease in its height and is dessicated.

The facet joints at the L5-S1 level bilaterally and on the left side at the L4-L5 level show degenerative changes.

A mild posterior disc bulge with small peridiscal osteophytes is seen at the L5-S1 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-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 :

18.0 mm at L1-L2
17.0 mm at L2-L3
16.0 mm at L3-L4
15.0 mm at L4-L5
17.0 mm at L5-S1.

IMPRESSION :

1. Probable spondylolysis of the L5 vertebra bilaterally with forward subluxation of the L5 over the S1 vertebra.

2. A small, postero-central disc herniation with peridiscal osteophytes, more to the right of the midline indenting the traversing right L5 nerve root at the L4-L5 level.

3. Facetal arthropathy at the L5-S1 level bilaterally and on the left side at the L4-L5 level.
