Name of the Patient : Abc Xyzhlmn / F / 63 yrs.
Referred by : Dr. Abc Xyzlaji.
Examination : M.R.I. of the Lumbo-sacral Spine.

CLINICAL PROFILE :

C/O backache radiating to the RLE with paresthesias since 11 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 a posterior disc herniation at the L5-S1 level with anterior indentation of the thecal sac and upon the traversing S1 nerve roots bilaterally, right more than left.

The lumbar intervertebral discs show loss of water content.

Diffuse fatty changes are seen within the lumbar vertebral bodies suggestive of osteoporosis. A hypointense area is seen within the L5 vertebral body on all the pulse sequences and which may represent sclerosis/fibrotic changes.

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 S1 level.





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

18.0 mm at L1-L2

17.0 mm at L2-L3

13.0 mm at L3-L4

11.0 mm at L4-L5

11.0 mm at L5-S1.

The hip joints were screened with 7 mm thick T1 Weighted axial and 5 mm thick STIR coronal images and do not reveal any diagnostic feature of note.

IMPRESSION :

The MRI features are suggestive of a posterior disc herniation at the L5-S1 level with indentation upon the traversing S1 nerve roots bilaterally, right more than left.
