Low back pain. The exam is somewhat motion degraded. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is mild retrolisthesis of L2 on L3. Alignment is otherwise within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position.Multilevel degenerative changes are seen, as described below. There is disc desiccation throughout the lumbar spine with relative sparing of L5-S1 level.L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: There are degenerative changes with significant endplate irregularity and moderate-severe disc narrowing. There is a disc bulge with left greater than right foraminal prominence. There is moderate left and mild right foraminal narrowing. There is prominent epidural fat at this level contributing to moderate spinal canal stenosis. There is thickening and redundancy of cauda equina nerve roots due to spinal canal stenosis.L3-L4: There are shallow biforaminal disc protrusions. Mild to moderate bilateral neural foraminal narrowing is seen. There is mild spinal canal stenosis at this level. There is evidence of facet arthropathy and ligamentum flavum thickening.L4-L5: There is diffuse disc bulge causing mild to moderate foraminal stenosis bilaterally. Mild lateral recess narrowing is also seen bilaterally. There is mild central canal stenosis at this level. There is evidence of facet arthropathy and ligamentum flavum thickening.L5-S1: No significant disc disease. No spinal canal or neural foraminal stenosis.Paraspinous soft tissues are within normal limits.
Multilevel mild-moderate degenerative changes. Findings are most pronounced at the L2-L3 level causing moderate central spinal canal stenosis and moderate left as well as mild right foraminal narrowing. Associated redundancy and thickening of cauda equina nerve roots. Underlying developmental central spinal canal narrowing secondary to prominence of dorsal epidural fat.
