Back pain and leg weakness Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is loss of normal lumbar lordosis. Alignment is otherwise maintained. Bone marrow signal is benign. The conus medullaris is normal in position.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: No significant disc disease. No spinal canal or neural foraminal stenosis.L4-L5: No significant disc disease. No spinal canal or neural foraminal stenosis.L5-S1: There is disk bulge with component of central disk protrusion which effaces the lateral recesses and contacts the bilateral traversing S1 nerve roots. No significant central canal stenosis. There is mild bilateral neural foramina stenosis.Paraspinous soft tissues are within normal limits.
Mild degenerative changes in the lumbar spine with disk protrusion at the L5-S1 level. There is contact of the traversing S1 nerve roots in the lateral recesses as well as mild narrowing of the L5-S1 neural foramina involving the exiting L5 nerve roots.
