Name of the Patient : Abc Xyzddin Samlmn / M / 36 yrs.
Referred by : Dr. Abc Xyzagwati.
Examination : M.R.I. of the Lumbo-sacral Spine.
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 a small posterior disc protrusion at the L5-S1 level with minimal indentation upon the S1 nerve roots. The right L5 and left S1 nerve roots appear slightly thicker. The L5-S1 facet joints show degenerative changes.
A small posterior disc herniation is seen at the L4-L5 level. The L4-L5 facet joints show mild degenerative change.
Fat is noted in the filum terminale at the L1 and L2 levels - a normal variant.
Slight increase in the epidural fat is noted at the L5 and S1 vertebral levels with trifoliate appearance of thecal sac, suggesting epidural lipomatosis.
The lumbar vertebral bodies and the intervertebral discs reveal normal signal intensity. The remaining facet joints and the visualized pre and paravertebral soft tissues are unremarkable.
The conus medullaris terminates at the D12 level and the thecal sac terminates at the L5 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
13.0 mm at L2-L3
11.0 mm at L3-L4
12.0 mm at L4-L5
11.0 mm at L5-S1.
1. A small posterior disc protrusion at the L5-S1 level with minimal indentation upon the S1 nerve roots. The right L5 and left S1 nerve roots appear slightly thickened.
2. A small posterior disc herniation at the L4-L5 level.
3. Degenerative changes of the L4-L5 and L5-S1 facet joints.
4. Epidural lipomatosis at the L5 and S1 vertebral levels.
