Name of the Patient : Abc XyzGhadigaolmn / M / 42 yrs.
Referred by : Dr. Abc Xyzhtekar.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to the LLE with paresthesias since 10-12 days.
H/O fall prior to this.

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 reduction in height of the L5-S1 disc and loss of water content of the L3-L4, L4-L5 and L5-S1 intervertebral discs.

A postero-central disc herniation with peridiscal osteophyte is noted at the L5-S1 level, indenting the dural theca anteriorly.

A fairly large, posteriorly extruded disc with peridiscal osteophytes is noted at the L4-L5 level with thecal sac compression. A sequestered disc fragment is noted in the anterior epidural space at this level.

A postero-central disc herniation with peridiscal osteophyte is noted at the L3-L4 level indenting the dural theca anteriorly.







The lumbar vertebral bodies and the remaining intervertebral discs reveal normal signal intensity. The 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 S1 level.

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

14.0 mm at L1-L2
14.0 mm at L2-L3
8.0 mm at L3-L4
6.0 mm at L4-L5
11.0 mm at L5-S1.

IMPRESSION :

1. A fairly large, posteriorly extruded disc with peridiscal osteophytes at the L4-L5 level with a sequestered disc fragment in the anterior epidural space at this level.

2. A postero-central disc herniation with peridiscal osteophyte at the L3-L4 level.

3. A postero-central disc herniation with peridiscal osteophyte at the L5-S1 level.

4. Lumbar canal stenosis at the L3-L4, L4-L5 and L5-S1 levels.
