Low back pain with radiculopathy 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.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 desiccation and disk height loss. There is large disk extrusion with inferior migration to the lower S1 level. Extruded disc components appear contiguous without definite evidence of sequestration. There is effacement of the right lateral recess. No significant central canal or neural foraminal stenosis.Paraspinous soft tissues are within normal limits.
Large L5-S1 disk extrusion with inferior migration to the lower S1 level. There is effacement of the right lateral recess which may be impinging on the traversing right S1 nerve root. No significant central spinal canal or neural foraminal stenosis.
