Spinal stenosis Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is minimal anterolisthesis of L3 on L4. Alignment is otherwise within normal limits. Bone marrow signal is benign. The conus medullaris is borderline low at the L2-L3 level. Multilevel degenerative changes are seen, as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: Mild disc bulge, ligamentum flavum thickening, and bilateral facet arthropathy. There is mild spinal canal stenosis. There is mild left and minimal right narrowing of the neural foramina. L3-L4: There is a disc bulge, bilateral facet arthropathy, and ligamentum flavum thickening contributing to moderate to severe spinal canal stenosis. There is mild bilateral neural foraminal stenosis. L4-L5: There is disc bulge, ligamentum flavum thickening, and bilateral facet arthropathy with severe spinal canal stenosis. There is mild to moderate bilateral neural foraminal stenosis.L5-S1: Mild disc bulge and bilateral facet arthropathy. No significant spinal canal stenosis. There is minimal narrowing of the neural foramina.Paraspinous soft tissues are within normal limits.
1. Multilevel degenerative changes in the lumbar spine with severe L4-L5 and moderate to severe L3-L4 spinal canal stenoses. 2. Neural foraminal stenoses is relatively worse at the L4-L5 level where there is mild-to-moderate bilateral neural foraminal stenosis.3. Borderline low conus at the L2-L3 level.
