Abnormal gait with flexed posture at the hip and right leg pain. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. Alignment is maintained. There are small Schmorl's nodes involving the endplates from the T11-L4 levels. There is severe disc height loss at the L3-L4 level with associated fatty endplate marrow signal changes. There is also disc height loss with suggestion of vacuum phenomena at the L5-S1 level. 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: No significant disc disease. No spinal canal or neural foraminal stenosis. There is bilateral facet arthropathy.L3-L4: There is a mild disc bulge, moderate bilateral facet arthropathy and ligamentum flavum thickening which contribute to mild to moderate central spinal canal stenosis. There is also mild to moderate right and mild left neural foraminal stenosis.L4-L5: Severe disc height loss and bilateral facet arthropathy. Partial effacement of the lateral recesses and minimal narrowing of the central spinal canal. There is moderate bilateral neural foraminal stenosis.L5-S1: Disc desiccation with suggestion of vacuum phenomena. Advanced bilateral facet arthropathy. There is no significant spinal canal stenosis. There is moderate left and mild right neural foraminal stenosis.Paraspinous soft tissues are within normal limits. There are cysts in the kidneys bilaterally.
Multilevel degenerative changes in the lumbar spine. There is up to mild to moderate spinal canal stenosis at the L4-L5 level. No high-grade spinal canal stenosis. Multilevel neural foraminal stenoses, worst at the bilateral L4-L5 levels. Additional details as above.
