Name of the Patient : Abc XyzPrasad Palmn / F / 38 yrs.
Referred by : Dr. Abc Xyzhtekar.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O radicular pain in the LLE with paresthesias since 2-3 years which has increased since 3 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 :

There is partial sacralization of the L5 vertebra on the left.

There is loss of water content of the L4-L5 intervertebral disc with reduction in height.

There a fairly large postero-central and left paracentral extruded disc at the L4-L5 level with inferior migration, thecal sac compression and indentation on the traversing left L5 nerve root. There is also facetal and slight ligamentum flavum hypertrophy at the L4-L5 level with resultant canal stenosis.

A minimal posterior disc bulge is noted at the L3-L4 level.

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

The rest of 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 level and the thecal sac terminates at the S1 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
20.0 mm at L2-L3
19.0 mm at L3-L4
8.0 mm at L4-L5
10.0 mm at L5-S1.

The left renal calculus seen on the X-rays is not well identified on the MRI.

IMPRESSION :

1. Partial sacralization of the L5 vertebra on the left.

2. A fairly large postero-central and left paracentral extruded disc at the L4-L5 level with inferior migration, compression of the thecal sac and indentation on the traversing left L5 nerve root. There is also facetal and slight ligamentum flavum hypertrophy at the L4-L5 level with resultant canal stenosis.
