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

CLINICAL PROFILE :

C/O backache with radiation of pain to the LLE 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.

MR myelogram was also obtained.

OBSERVATION :

There is probable spondylolysis at the L5, bilaterally, with minimal forward translation of the L5 over the S1 vertebra (kindly correlate with plain radiographs).

A posterior disc extrusion with a peridiscal osteophyte is seen at the L5-S1 level. Superior migration of the disc is noted with a disc portion seen to lie within the left lateral recess of the L5 vertebra with impingement of the traversing left L5 nerve root.

The lumbar facet joints show mild degenerative changes.

The L5-S1 intervertebral disc shows loss of water content.

The lumbar vertebral bodies and the remaining intervertebral discs reveal normal signal intensity. The visualized pre and paravertebral soft tissues are unremarkable.

The conus medullaris terminates at the L1 level and the thecal sac terminates at the S2 level.

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
12.0 mm at L3-L4
14.0 mm at L4-L5
14.0 mm at L5-S1.

IMPRESSION :

1. Probable spondylolysis at the L5, bilaterally with minimal forward translation of the L5 over the S1 vertebra.

2. A posterior disc extrusion with a peridiscal osteophyte at the L5-S1 level. A disc portion is seen to lie within the left lateral recess of the L5 vertebra with impingement of the traversing left L5 nerve root.
