Name of the Patient : Abc Xyzam L. Dalmn / M / 70 yrs.
Referred by : Dr. Abc Xyznkar.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O weakness of BLE.

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 loss of water content of the lumbar intervertebral discs with reduction in height of the L4-L5 intervertebral disc.

A posteriorly bulging disc with peridiscal osteophytes is noted at the L4-L5 level with slight bilateral neural foraminal narrowing. Facetal and ligamentum flavum hypertrophy is noted at this level with a tight lumbar canal.

A small posterior disc bulge with a left far lateral bulging disc is noted at the L3-L4 level with slight left neural foraminal narrowing and indentation upon the foraminal left L3 nerve root.

Type II degenerative marrow changes are noted adjacent to the L4-L5 disc.

The rest of 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 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 :

15.0 mm at L1-L2
15.0 mm at L2-L3
13.0 mm at L3-L4
11.0 mm at L4-L5
11.0 mm at L5-S1.

Screening images of the dorsal spine and the dorso-lumbar region do not reveal any significant feature of note.

IMPRESSION :

1. A posteriorly bulging disc with peridiscal osteophytes at the L4-L5 level with facetal and ligamentum flavum hypertrophy at this level with a tight lumbar canal.

2. A small posterior disc bulge with a left far lateral bulging disc at the L3-L4 level with indentation upon the foraminal left L3 nerve root.
