Radicular pain in the left lower extremity 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.Examination is mildly motion degraded. There is developmental narrowing of the lumbar spinal canal with superimposed mild degenerative changes as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: Disc desiccation with mild bulge, eccentric to the right. No spinal canal or neural foraminal stenosis.L3-L4: Disc desiccation and disc bulge. No spinal canal or neural foraminal stenosis.L4-L5: Disc desiccation with left foraminal annular fissure and small disc protrusion (series 10, image 19). There is contact of the left L5 nerve root in the lateral recess. No significant central spinal canal stenosis or neural foraminal stenosis.L5-S1: No significant disc disease. No spinal canal or neural foraminal stenosis.Paraspinous soft tissues are within normal limits.
1. Left foraminal annular fissure at L4-L5 with small disc protrusion. There is contact and possible impingement of the left L5 nerve root in the lateral recess. No significant central spinal canal stenosis at any level or neural foraminal stenosis.2. Development of narrowing of the lumbar spinal canal.
