Left leg radiculopathy, evaluate for stenosis Five lumbar type vertebral bodies are present. Vertebral body heights are within normal limits with minimal anterior wedging at T12 which may be physiologic. There is grade 1 anterolisthesis of L3 on L4 and L4 on L5. There is advanced bilateral facet arthropathy at L3-L4 and L4-L5. 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: Minimal disk bulge and prominence of the epidural fat resulting in mild spinal canal narrowing. There is also mild bilateral neural foraminal narrowing. L3-L4: There is severe spinal canal stenosis related to anterolisthesis with disc uncovering and bulge, significant thickening of the ligamentum flavum, and advanced facet arthropathy. There is mild to moderate bilateral neural foraminal narrowing. L4-L5: There is moderate to severe spinal canal stenosis related to anterolisthesis with disc uncovering and bulge, significant thickening of the ligamentum flavum, and advanced facet arthropathy. There is moderate to severe right neural foraminal narrowing and moderate left neural foraminal narrowing.L5-S1: There is disk bulge eccentric to the right with mild right neural foraminal narrowing. No significant spinal canal or left neural foraminal narrowing.Paraspinous soft tissues are within normal limits. Bilateral hip arthroplasties.
1. Degenerative changes with severe spinal canal stenosis at L3-L4 and moderate to severe spinal canal stenosis at L4-L5.2. Advanced facet arthropathy at L3-L4 and L4-L5 with grade 1 anterolisthesis of L3 on L4 and L4 on L5.3. Neural foraminal stenosis at L3-L4 and L4-L5 as detailed above.
