Name of the Patient : Abc Xyzne Dslmn / F / 62 yrs.
Referred by : Dr. Abc Xyzah / Dr. Abc Xyzani.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to the LLE since 1 year.

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 :

A small posterior disc herniation with peridiscal osteophytes is seen to indent the thecal sac at the L4-L5 level with resultant mild neural foraminal narrowing bilaterally at this level.

There is a suspicious break of the pars interarticularis of the L5 vertebra bilaterally. Please correlate with plain radiographs.

A postero-central disc protrusion is noted at the L5-S1 level.

The L4-L5 facet joints show hypertrophic degenerative changes. Also seen is mild ligamentum flavum hypertrophy at the L4-L5 and L5 levels.

The lumbar intervertebral discs show loss of water content.

The lumbar vertebral bodies 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 :

20.0 mm at L1-L2
20.0 mm at L2-L3
15.0 mm at L3-L4
12.0 mm at L4-L5
16.0 mm at L5-S1.

IMPRESSION :

The MRI features are suggestive of :

1. A small posterior disc herniation with peridiscal osteophytes at the L4-L5 level.

2. Hypertrophic facetal arthropathy at the L4-L5 level and
mild ligamentum flavum hypertrophy at the L4-L5 and L5 levels.

3. A postero-central disc protrusion at the L5-S1 level.

4. Probable spondylolysis of the L5 vertebra bilaterally.
Please correlate with plain radiographs.
