Right leg tingling Conventional anatomy with 5 lumbar type vertebral bodies are presumed, with the most inferior well-defined disc space labeled L5-S1. Vertebral body heights are within normal limits. There is grade 1 anterolisthesis of L4 and L5 as well as minimal retrolisthesis of L5 on S1. Bone marrow signal is benign. The conus medullaris is normal in position.Multilevel degenerative changes are seen, as described below:L1-L2: Minimal disc bulge, ligamentum flavum thickening, and facet arthropathy. No spinal canal or neural foraminal stenosis.L2-L3: Minimal disc bulge, ligamentum flavum thickening, and facet arthropathy. No spinal canal or neural foraminal stenosis.L3-L4: Disc bulge eccentric to the left. There is moderate bilateral facet arthropathy. There is partial effacement of the left lateral recess as well as mild central canal narrowing. Neural foramina are patent.L4-L5: Grade 1 anterolisthesis and mild disc bulge with advanced bilateral facet arthropathy and ligamentum flavum thickening. There is moderate spinal canal stenosis including partial effacement of the bilateral lateral recesses. There is mild narrowing of the neural foramina, right worse than left. L5-S1: Minimal retrolisthesis and disc bulge. There is no significant spinal canal stenosis. Bilateral facet arthropathy. There is mild narrowing of the neural foramina, left relatively greater than right.Paraspinous soft tissues are within normal limits.
1. Multilevel degenerative changes in the lumbar spine, worst at the L4-L5 level, where there is moderate moderate spinal canal stenosis and evidence of degenerative grade 1 anterolisthesis. There is mild neural foraminal stenosis at this level, right relatively greater than left.2. Multilevel facet arthropathy, worst at L4-L5 and L3-L4 and to a lesser degree at additional levels.
