Name of the Patient : Abc Xyza Gorlmn / F / 41 yrs.
Referred by : Dr. Abc Xyztalkar.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache radiating to the RLE with paresthesias since 9 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 loss of water content of the L3-L4 and L5-S1 intervertebral discs.
There is Grade I spondylolisthesis of the L5 over the S1 vertebra with spondylolysis at L5 bilaterally. There is resultant compromise of the neural foramina bilaterally and impingement of the exiting L5 nerve roots at this level. A small posterior disc bulge is also noted at the L5-S1 level.
Slight facetal hypertrophy is noted at the D12-L1 level on the right and at the L5-S1 level bilaterally.
Slight ligamentum flavum hypertrophy is noted at the L5-S1 level.
Type II degenerative changes are seen in the L5 and S1 vertebral bodies adjacent to the L5-S1 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.
..2/.
The conus medullaris terminates at the L1 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 :
14.0 mm at L1-L2
14.0 mm at L2-L3
15.0 mm at L3-L4
14.0 mm at L4-L5
13.0 mm at L5-S1.
IMPRESSION :
1. Grade I spondylolisthesis of the L5 over the S1 vertebra with spondylolysis at L5 bilaterally and
resultant compromise of the neural foramina bilaterally and impingement of the exiting L5 nerve roots at this level.
2. Slight facetal hypertrophy at the D12-L1 level on the right and at the L5-S1 level bilaterally.
3. Slight ligamentum flavum hypertrophy at the L5-S1 level.
