Name of the Patient : Abc XyzB. Jlmn / M / 45 yrs.
Referred by : Dr. Abc Xyzpadia.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to BLE with paresthesias (right more than left) since 4 months.

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 vertebral body is as marked on the film.

There is loss of normal lumbar lordosis and loss of water content of the L3-L4, L4-L5 and L5-S1 intervertebral discs.

There is a fairly large, postero-central and right paracentral extruded disc with peridiscal osteophytes at the L5-S1 level with thecal sac compression and indentation on the traversing right S1 nerve root. Inferior migration of the disc fragment is noted. Bilateral postero-lateral and far lateral disc bulges are also noted at the L5-S1 level narrowing the neural foramina bilaterally at this level.

A posteriorly bulging disc is noted at the L4-L5 level with bilateral neural foraminal narrowing.






A left postero-lateral disc bulge is noted at the L3-L4 level.

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

The facet joints at the L5-S1 level show slight degenerative changes bilaterally.

Type II degenerative marrow changes are noted adjacent to the L5-S1 disc.

A hemangioma with fat content is noted in the L1 vertebral body.

The rest of the lumbar and sacral vertebral bodies show focal fatty change. 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.

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

20.0 mm at L1-L2
17.0 mm at L2-L3
19.0 mm at L3-L4
19.0 mm at L4-L5
10.0 mm at L5-S1.
