Pain, radiating down left leg Please note for the purposes of numbering, there is transitional anatomy with the first nonrib-bearing vertebral body labeled L1. As such there are 4 lumbar type vertebral bodies and a transitional segment labeled S1. Vertebral body heights are within normal limits. There is some loss of lumbar lordosis. There is grade 1 anterolisthesis of L4 on S1. 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: There is disc desiccation and left foraminal and far lateral disc bulge. There is partial effacement of the left lateral recess as well as mild left neural foraminal stenosis. There may be impingement of the exited left sided nerve root extraforaminally. Right neural foramen is patent. Moderate bilateral facet arthropathy.L4-S1: There is disc bulge and advanced bilateral facet arthropathy. There is no significant spinal canal stenosis. There is moderate to severe right and mild left neural foraminal stenosis. There may be impingement of the exiting right-sided nerve root.Paraspinous soft tissues are within normal limits.
1. Please note transitional anatomy and numbering scheme with 4 lumbar type vertebral bodies.2. Degenerative changes are present as described above without significant spinal canal stenosis. There is left-sided neural foraminal stenosis at L3-L4 and right-sided neural foraminal stenosis at L4-S1 as described above.3. Grade 1 degenerative spondylolisthesis at L4 S1.
