Sciatica, evaluate for disc disease and nerve impingement. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. Alignment is within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position at the upper L2 level.Multilevel degenerative changes are seen, as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: No significant disc disease. No spinal canal or neural foraminal stenosis.L3-L4: Disk desiccation and minimal bulge. Minimal left neural foraminal narrowing. Otherwise no spinal canal or neural foramina stenosis. L4-L5: Disk desiccation and minimal bulge. No spinal canal or neural foraminal stenosis.L5-S1: Disk desiccation and minimal bulge. No spinal canal or neural foraminal stenosis.Incidentally seen are conjoined left L5 and S1 nerve roots. Mild facet arthropathy is seen at L3-L4, L4-L5, and L5-S1. There is edema and joint distention associated with the right L3-L4 and L4-L5 facet joints. Mild degenerative changes at the sacroiliac joints also noted.
1. Mild degenerative changes in the lumbar spine including disc bulges as detailed above. Minimal left L3-L4 neural foramina narrowing. Otherwise, no significant spinal canal or neural foramina stenosis is seen at any level in the lumbar spine.2. Facet arthropathy in the lumbar spine. There is edema and joint distention associated with the right L3-L4 and right L4-L5 facet joints, which is favored to be on a degenerative basis.  3. Conjoined left L5 and S1 nerve roots incidentally noted.
