Pain radiating down left leg. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is minimal compression deformity involving the right aspect of the superior L1 endplate. There is grade 1 anterolisthesis of L4 on L5, L3 on L4, and to a minimal degree L2 on L3. There is mild multilevel disc desiccation. Bone marrow signal is benign. The conus medullaris is normal in position.Multilevel degenerative changes are seen, as described below:L1-L2: Mild disc bulge, eccentric to the right. There is mild right-sided neural foraminal stenosis. No spinal canal or left neural foraminal stenosis.L2-L3: Mild disc bulge, ligamentum flavum thickening and facet arthropathy. No spinal canal stenosis. Minimal narrowing of the bilateral neural foramina. L3-L4: Mild disc uncovering and bulge, ligamentum flavum thickening and moderate bilateral facet arthropathy. There is no significant spinal canal stenosis. There is mild to moderate right and mild left neural foraminal stenosis.L4-L5: Disc uncovering and disc bulge with small left foraminal disc extrusion. There is also ligamentum flavum thickening and moderate bilateral facet arthropathy. There is moderate left and mild right neural foraminal stenosis. There is no significant spinal stenosis.L5-S1: No significant disc disease. No spinal canal or neural foraminal stenosis.Paraspinous soft tissues are within normal limits. Multiple left-sided renal cysts.
1. Multilevel degenerative changes throughout the lumbar spine. There is moderate left-sided neural foraminal stenosis at L4-L5 where there is suspected impingement of the left L4 nerve root.2. Additional details, including multilevel facet arthropathy with grade 1 anterolistheses, as above. No significant spinal canal stenosis at any level.
