Name of the Patient : Abc Xyzddin Sk. Glmn / M / 42 yrs.
Referred by : Dr. Abc Xyzhtekar.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache radiating to the LLE since 1 month and paresthesias in the RLE 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 sacralization of the L5 vertebra and it is as marked on the film. (Please correlate with plain radiographs). There is slight retrolisthesis of the L3 vertebra over the L4 vertebra.
A posterior disc herniation is seen to indent the thecal sac and narrow both neural foramina at the L3-L4 level.
A posterior disc bulge is noted at the L4-L5 level. Bilateral far lateral (extraforaminal) disc bulges are seen at the L4-L5 level.
Ligamentum flavum hypertrophy is seen at the L3-L4 and L4-L5 levels. Facetal hypertrophy is evident at the L1-L2, L2-L3, L3-L4 and L4-L5 levels.
Conjoint nerve roots are noted on the right side at the L5 level.
The lumbar intervertebral discs show mild loss of water content.
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 L1 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 :
12.0 mm at L1-L2
13.0 mm at L2-L3
7.0 mm at L3-L4
10.0 mm at L4-L5
8.0 mm at L5-S1.
1. Sacralization of the L5 vertebra (Please correlate with plain radiographs).
2. A posterior disc herniation with canal stenosis at the L3-L4 level.
3. A posterior disc bulge with a tight canal at the L4-L5 level.
4. Ligamentum flavum hypertrophy at the L3-L4 and L4-L5 levels.
5. Facetal arthropathy at the L1-L2, L2-L3, L3-L4 and L4-L5 levels.
