Right lumbar radiculopathy, reduced patellar reflex. Five lumbar type vertebral bodies are present. Vertebral body heights are within normal limits. Alignment is grossly maintained with perhaps minimal anterolisthesis of L3 on L4 and L4 on L5. Bone marrow signal is benign with prominent edematous/Modic 1 type endplate marrow signal changes involving the right aspect of the L4 and L5 vertebral bodies. The conus medullaris is normal in position.Multilevel degenerative changes are seen, including disc height loss at L3-L4 and L4-L5 with vacuum phenomena. Individual levels as described below:L1-L2: Minimal disc bulge. No spinal canal or neural foraminal stenosis.L2-L3: Minimal disc bulge. No spinal canal or neural foraminal stenosis.L3-L4: Mild disc bulge, ligamentum flavum thickening and facet arthropathy contribute to mild narrowing of the spinal canal. There is mild right and minimal left neural foraminal narrowing.L4-L5: There is mild disc bulge, moderate bilateral facet arthropathy, and ligamentum flavum thickening. There is moderate degree of spinal canal stenosis. There is severe right and minimal left neural foraminal stenosis.L5-S1: Mild disc bulge, ligamentum flavum thickening, and bilateral facet arthropathy. There is no significant spinal canal stenosis. There is mild to moderate right and mild left neural foraminal stenosis.Paraspinous soft tissues are within normal limits.
Multilevel degenerative changes in the lumbar spine, worst at the L4-L5 level. There is moderate L4-L5 spinal canal stenosis. There is also severe right L4-L5 neural foraminal stenosis which is suspected to be impinging on the exiting right L4 nerve root.
