Back pain, left-sided sciatica For the purposes of numbering there are 5 nonrib-bearing lumbar type vertebral bodies. The last well-formed disc is at L5-S1.There is mild loss of lumbar lordosis. Alignment is otherwise anatomic. The vertebral bodies are preserved in height. There is minimal degenerative marrow signal subjacent to the endplates at L5-S1. The L5-S1 in addition to L1-L2 discs show desiccation. Otherwise, the disks are preserved. The tip of the conus medullaris lies normally at the L1-L2 level. The conus medullaris shows normal signal. There are mild osteoarthritic changes involving the visualized sacroiliac joints.Individual levels as below:T11-T12 and T12-L1: No disc herniation and no spinal canal or foraminal stenosis.L1-L2: Right paracentral disc protrusion but no significant spinal canal or foraminal stenosis.L2-L3, L3-L4, and L4-L5: No disc herniation and no spinal canal or foraminal stenosis.L5-S1: Disc bulge and minimal left more than right endplate osteophyte formation and facet arthropathy. No significant spinal canal stenosis. There is mild right and mild to moderate left neural foraminal stenosis.
Mild degenerative changes in the lumbar spine, relatively worst at the L5-S1 level. There is mild to moderate neural foraminal stenosis at the left L5-S1 level which may be effecting the left L5 nerve root.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
