Name of the Patient : Abc Xyzar Botlmn / M / 27 yrs.
Referred by : Dr. Abc Xyzodak.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache with numbness in BLE.
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.
There is loss of water content of the L1-L2 and L5-S1 intervertebral discs.
There is Grade I spondylolisthesis of the L5 vertebra over the S1 vertebra with probable spondylolysis at L5 bilaterally. A resultant pseudoposterior disc herniation is seen at the L5-S1 level with minimal indentation on the traversing right S1 nerve root. Bilateral far lateral (extraforaminal) disc bulges are seen to indent the exiting L5 nerve roots at the L5-S1 level.
A posteriorly bulging disc with peridiscal osteophytes is noted at the L4-L5 level with slight facetal hypertrophy and a tight lumbar canal at this level.
A minimal posterior disc bulge is noted at the L3-L4 level.
A small postero-central protruded disc is noted at the L1-L2 level.
Slight facetal hypertrophy is also noted in the rest of the lumbar region.
A hemangioma with fat content (hyperintense on all the pulse sequences) is noted in the L2 vertebral body.
The rest of the lumbar vertebral bodies and the remaining intervertebral discs reveal normal signal intensity. The visualized pre and paravertebral soft tissues are unremarkable.
The conus medullaris terminates at the D12 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 :
11.0 mm at L1-L2
11.0 mm at L2-L3
11.0 mm at L3-L4
7.0 mm at L4-L5
6.0 mm at L5-S1.
1. Grade I spondylolisthesis of the L5 vertebra over the S1 vertebra with probable spondylolysis at L5 bilaterally with a pseudoposterior disc herniation at the L5-S1 level minimally indenting the traversing right S1 nerve root.
2. A posteriorly bulging disc with peridiscal osteophytes at the L4-L5 level with slight facetal hypertrophy and a tight lumbar canal at this level.
3. A small postero-central protruded disc at the L1-L2 level.
4. Slight facetal hypertrophy in the rest of the lumbar region.
