Name of the Patient : Abc Xyz Ulmn / M / 25 yrs.
Referred by : Dr. Abc Xyzar.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating 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.

OBSERVATION :

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

There is a posterior disc herniation at the L4-L5 level with anterior indentation of the thecal sac and left neural foraminal narrowing. The L4-L5 facet joints show hypertrophic degenerative changes. Ligamentum flavum hypertrophy is also noted at this level with resultant central and lateral canal stenosis.

A small postero-central disc herniation is seen at the L5-S1 level.

The L3-L4 and L5-S1 facet joints show mild degenerative changes.

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

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 L5 level.

The antero-posterior dimensions of the lumbar canal at the level of the intervertebral discs are as follows :

15.0 mm at L1-L2
14.0 mm at L2-L3
12.0 mm at L3-L4
10.0 mm at L4-L5
10.0 mm at L5-S1.

IMPRESSION :

1. A posterior disc herniation at the L4-L5 level with left neural foraminal narrowing, facetal arthropathy, ligamentum flavum hypertrophy and resultant central and lateral canal stenosis.

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