Name of the Patient : Abc XyzIchhaplmn / M / 69 yrs.
Referred by : Dr. Abc Xyznshah.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache with pain radiating to the LLE with tingling and bowel dysfunction since 15 days.
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 all the lumbar intervertebral discs with reduction in height of the L4-L5 and L5-S1 intervertebral discs.
There is slight forward translation of the L4 over the L5 vertebral body.
There is a fairly large posteriorly extruded disc at the L5-S1 level with inferior migration of the disc, posterior to the S1 vertebral body with compression upon the thecal sac and the traversing S1 nerve roots bilaterally and canal stenosis.
A posterior disc herniation is seen at the L4-L5 level with anterior indentation of the thecal sac. Mild ligamentum flavum hypertrophy is seen at the L4-L5 and L5 levels with facetal hypertrophy and resultant tight lumbar canal at this level.
A posterior disc bulge is seen at the L3-L4 level. Facetal arthropathy is also seen at this level.

The lumbar vertebral bodies 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 D12-L1 level and the thecal sac terminates at the S1-S2 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
14.0 mm at L3-L4
14.0 mm at L4-L5
9.0 mm at L5-S1.
Note is made of a cyst arising from the inferior pole of the left kidney.
The cervical and dorsal spines were screened with 4 mm thick T2 Weighted sagittal images and do not reveal any significant feature of note.
IMPRESSION :
The MRI features are suggestive of :
1. A fairly large posteriorly extruded disc at the L5-S1 level with inferior migration of the disc, posterior to the S1 vertebral body indenting the
traversing S1 nerve roots bilaterally and canal stenosis.
2. A posterior disc herniation at the L4-L5 level with mild ligamentum flavum hypertrophy at the L4-L5 and L5 levels with facetal hypertrophy and resultant tight lumbar canal at this level.
3. A posterior disc bulge with facetal arthropathy at the L3-L4 level.
