Name of the Patient : Abc Xyzm Chlmn / M / 65 yrs.
Referred by : Dr. Abc Xyznna.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to the LLE with paresthesias since 1 year which has increased since 15 days.

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 left paracentral and left postero-lateral disc herniation at the L4-L5 level with antero-lateral compression of the thecal sac and left neural foraminal narrowing. There is indentation upon the extraforaminal portion of the left L4 nerve root. There is suggestion of inflammation of the left L5 nerve root. Facetal and ligamentum flavum hypertrophy is also noted at the L4-L5 and L5 levels with resultant left lateral stenosis.

Right far lateral disc herniations are noted at the L4-L5 and L3-L4 levels with slight indentation upon the extraforaminal portion on the right L4 and L3 nerve roots, respectively.

Small posterior disc herniations are noted at the L2-L3 and L5-S1 levels. The lumbar intervertebral discs show loss of water content.
Scan-00009

The L5-S1 facet joint on the left shows slight degenerative change and the facet joints at the L1-L2 and L3-L4 levels appear hypertrophied.

The lumbar vertebral bodies reveal normal signal intensity. The remaining 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 S2 level.

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

16.0 mm at L1-L2
15.0 mm at L2-L3
16.0 mm at L3-L4
9.0 mm at L4-L5
10.0 mm at L5-S1.

IMPRESSION :

1. A left paracentral and left postero-lateral disc herniation at the L4-L5 level with indentation upon the extraforaminal portion of the left L4 nerve root. There is ligamentum flavum and facetal hypertrophy at the L4-L5 and L5 levels with canal stenosis. There is suggestion of inflammation of the left L5 nerve root.

2. Right far lateral disc herniations at the L4-L5 and L3-L4 levels with slight indentation upon the extraforaminal portion on the right L4 and L3 nerve roots, respectively.

3. Small posterior disc herniations at the L2-L3 and L5-S1 levels.

4. Facetal hypertrophy at the L1-L2 and L3-L4 levels and slight facetal arthropathy at the L5-S1 level on the left.
