Leg pain, lumbar radiculopathy Five non-rib-bearing lumbar type vertebral bodies are presumed to be present. L5 demonstrates transitional anatomy with articulation of the left L5 transverse process with the sacrum. Vertebral body heights are within normal limits. There is exaggeration of lumbar lordosis. Alignment is otherwise grossly maintained. 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. There is prominence of the dorsal epidural fat and bilateral facet arthropathy with mild spinal canal stenosis. No significant neural foraminal stenosis.L3-L4: There is disc bulge, advanced bilateral facet arthropathy, and ligamentum flavum thickening resulting in moderate to severe spinal canal stenosis. There is mild to moderate bilateral neural foraminal stenosis. L4-L5: There is a central disc extrusion, advanced bilateral facet arthropathy, and ligamentum flavum thickening resulting in severe spinal canal stenosis. There is moderate right and moderate to severe left neural foraminal stenosis. L5-S1: Minimal disc bulge. Advanced bilateral facet arthropathy. No significant spinal canal or neural foraminal stenosis.Paraspinous soft tissues are within normal limits.
Advanced degenerative changes in the lumbar spine with high-grade spinal canal stenosis at the L3-L4 and L4-L5 levels. Neural foraminal stenosis is worst at the L4-L5 level where there is moderate right and moderate to severe left neural foraminal stenosis. There is also advanced facet arthropathy in the mid and lower lumbar spine. Please see details above.
