Left lower extremity radiculopathy with L3-L4 retrolisthesis, evaluate for nerve compression Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is exaggeration of the lumbar lordosis. There is grade 1 anterolisthesis of L3 on L4 as well as mild retrolisthesis of L2 on L3. 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: Moderate loss of disk height with vacuum phenomena. Minimal retrolisthesis and mild disk bulge, eccentric to the left. There is ligamentum flavum thickening and mild facet arthropathy. There is mild spinal canal and mild bilateral neural foramina stenosis.L3-L4: Mild anterolisthesis with disk uncovering, advanced bilateral facet arthropathy, and ligamentum flavum thickening. There is moderate to severe spinal canal stenosis as well as mild to moderate bilateral neural foraminal stenosis.L4-L5: Significant disk height loss and vacuum phenomena. There is minimal disk bulge, ligamentum flavum thickening, as well as facet arthropathy. There is no significant spinal canal stenosis. Minimal bilateral foraminal narrowing.L5-S1: There is loss of disk height with associated endplate marrow signal changes. There is minimal disk bulge and left foraminal osteophyte as well as facet arthropathy. There is mild to moderate right and moderate left neural foraminal stenosis. Paraspinous soft tissues are within normal limits. Incidentally seen is a small perineural cyst at the S2 level.
1. Multilevel degenerative changes in the lumbar spine as detailed above. There is grade 1 L3 on L4 anterolisthesis and minimal L2 on L3 retrolisthesis.2. Moderate to severe spinal canal stenosis at L3-L4.3. There is moderate left L5-S1 neural foraminal stenosis which may be impinging on the left L5 nerve root. There is also mild to moderate left L3-L4 neural foraminal narrowing.4. Facet arthropathy throughout the lumbar spine, worst at L3-L4.
