Severe back pain radiating down right leg 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 and L4 on L5. Alignment is otherwise grossly maintained. Bone marrow signal is benign. The conus medullaris is normal in position.Multilevel degenerative changes are seen including multilevel disc desiccation. Individual levels as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: Mild disc bulge with foraminal components. There is no significant spinal canal or right neural foraminal narrowing. There is minimal left neural foraminal narrowing.L3-L4: There is a disc bulge with a small central extrusion. There is also ligamentum flavum thickening and bilateral facet arthropathy at this level contributing to mild spinal canal stenosis. There is mild bilateral, left worse than right, neural foraminal stenosis. L4-L5: Disc bulge with a small central extrusion, facet arthropathy and ligamentum flavum thickening. No significant spinal canal stenosis. There is up to moderate left neural foraminal stenosis and mild right neural foraminal narrowing.L5-S1: Minimal disc bulge without significant spinal canal stenosis. There is mild bilateral neural foraminal stenosis. There is right-sided facet arthropathy.Paraspinous soft tissues are within normal limits.
Multilevel degenerative changes in the lumbar spine, relatively worse at the L3-L4 and L4-L5 levels. There is mild spinal canal stenosis at L3-L4. There is moderate left L4-L5 neural foraminal stenosis. Additional details as above.
