Name of the Patient : Abc Xyza R. Klmn / F / 48 yrs.
Referred by : Dr. Abc Xyzrekh.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to the RLE with paresthesias 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 :

There is a postero-central and right paracentral disc extrusion at the L5-S1 level with anterior indentation of the thecal sac. There is inferior migration of the disc fragment which is seen to lie in the right lateral recess of the S1 vertebra with mild indentation upon the right S1 nerve root.

A small, postero-central and bilateral far lateral disc herniation is seen at the L4-L5 level.

Mild ligamentum flavum and facetal hypertrophy is seen at the L5 and S1 levels. The L4-L5 and L5-S1 intervertebral discs show loss of water content.

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 S2 level.
- 2 - Scan-00009

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

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

IMPRESSION :

The MRI features are suggestive of :

1. A postero-central and right paracentral disc extrusion at the L5-S1 level with inferior migration of the disc fragment which is seen to lie in the right lateral recess of the S1 vertebra, with mild indentation upon the right S1 nerve root.

2. A small, postero-central and bilateral far lateral disc herniations at the L4-L5 level.

3. Mild ligamentum flavum and facetal hypertrophy at the L5 and S1 levels.
