Disc protrusion, foraminal stenosis. Right leg numbness, pain shooting down laterally, anteriorly. Five lumbar type vertebral bodies are present. Vertebral body heights are within normal limits. There is mild loss of lumbar lordosis as well as grade 1 anterolisthesis of L4 on L5 and minimal L5 on S1 retrolisthesis. Bone marrow signal is benign with T1 hyperintense focus involving the L2 vertebral body consistent with hemangioma and multilevel endplate fatty signal changes on a degenerative basis. The conus medullaris is normal in position.Degenerative changes are seen throughout the lumbar spine including multilevel vacuum disc phenomena, better appreciated on recent CT, and disc space narrowing, worst at the L5-S1 levels. Individual levels as 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: Mild disc bulge and prominence of the epidural fat resulting in mild spinal canal narrowing. There is mild right and minimal left neural foraminal stenosis.L4-L5: Grade 1 anterolisthesis. There is edema involving the posterior aspect of the disc, most likely on a degenerative basis. Vacuum phenomena better seen on recent CT. There is bilateral facet arthropathy, worse on the left. There is also mild disc bulge eccentric to the right. There is resulting mild to moderate stenosis involving the proximal aspect of the right neural foramen. There is minimal left neural foraminal narrowing. No significant central canal narrowing.L5-S1: Minimal retrolisthesis. Severe loss of disc height. There is facet arthropathy, worse on the left than the right. No significant spinal canal narrowing. There is mild bilateral neural foraminal narrowing, relatively worse on the left. There is a prominent left lateral vertebral osteophyte.Evidence of left nephrectomy. Paraspinous soft tissues are within normal limits.
Multilevel degenerative changes in the lumbar spine including mild spinal canal stenosis at the L3-L4 level. There is also also mild to moderate right neural foraminal narrowing at the L4-L5 level where there is possible impingement of the right L4 nerve root. Additional levels as above.
