Name of the Patient : Abc Xyzhlal Majulmn / M / 44 yrs.
Referred by : Dr. Abc XyzV. Shah.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache, increased since 8 days.
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 retrolisthesis of the L4 over the L5 vertebral body.
A posterior disc herniation is seen at the L4-L5 level with anterior indentation of the thecal sac and bilateral neural foraminal narrowing. The L4-L5 facet joints show degenerative changes with minimal effusion within the right facet joint. There is resultant tight canal and mild indentation on the foraminal portion of the L4 nerve roots.
A small posterior disc herniation is seen at the L3-L4 level and a posterior disc bulge is noted at the L5-S1 level.
Schmorls nodes are noted at the L3-L4 and L4-L5 levels.
The lumbar intervertebral discs show loss of water content. The L5-S1 facet joints show degenerative changes, bilaterally.
Type I degenerative changes are noted in L4 vertebral body adjacent to the L4-L5 intervertebral disc.
Fat is noted within the filum terminale at the L2 and L3 levels - a normal variant.
The rest of the lumbar vertebral bodies reveal normal signal intensity. The remaining 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 :
17.0 mm at L1-L2
14.0 mm at L2-L3
9.0 mm at L3-L4
9.0 mm at L4-L5
9.0 mm at L5-S1.
1. Retrolisthesis of the L4 over the L5 vertebral body.
2. A posterior disc herniation at the L4-L5 level with facetal arthropathy and minimal effusion within the right facet joint with resultant tight canal and mild indentation on the foraminal portion of the L4 nerve roots.
