Name of the Patient : Abc Xyz R.lmn / M / 32 yrs.
Referred by : Dr. Abc Xyzrekh.
Examination : M.R.I. of the Lumbo-sacral Spine.
CLINICAL PROFILE :
C/O backache radiating to the LLE with paresthesias.
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.
FEW IMAGES SHOW PATIENT MOTION.
A large postero-central disc extrusion is seen to indent the thecal sac at the L5-S1 level. A disc portion is seen to lie in the anterior epidural space at the S1 level with resultant impingement of the traversing S1 nerve roots bilaterally, left more than right.
A posterior disc bulge is noted at the L4-L5 level.
The L5-S1 facet joints show degenerative changes. The L5-S1 intervertebral disc shows loss of water content.
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.
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 :
15.0 mm at L1-L2
15.0 mm at L2-L3
16.0 mm at L3-L4
14.0 mm at L4-L5
10.0 mm at L5-S1.
The MRI features are suggestive of :
1. A large postero-central disc extrusion with a tight canal at the L5-S1 level. A disc portion is seen to lie in the anterior epidural space at the S1 level with resultant impingement of the traversing S1 nerve roots bilaterally, left more than right.
2. Facetal arthropathy at the L5-S1 level.
