Left foot anterior calf numbness and left foot drop. Evaluate for lumbar disc disease or myeloma lesion. Five lumbar type vertebral bodies are present. Vertebral body heights are within normal limits. Alignment is within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position.There are mild degenerative changes including multilevel disc desiccation but without significant height loss. Additional details 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.L3-L4: Mild disc bulge and mild facet arthropathy contribute to mild bilateral neural foraminal narrowing, left relatively greater than right. No significant spinal canal stenosis.L4-L5: Mild disc bulge and mild facet arthropathy. There is mild to moderate right and minimal left neural foraminal narrowing. No significant spinal canal stenosis. L5-S1: No significant disc disease. There is moderate degree of facet arthropathy bilaterally, left worse than right. No significant spinal canal or neural foraminal stenosis. Paraspinous soft tissues are within normal limits. Multiple cysts in the kidneys are again seen.
1. No suspicious lesions to suggest multiple myeloma.2. Mild multilevel degenerative changes in the lumbar spine as detailed above. No significant spinal canal stenosis at any level. Neural foraminal stenosis is relatively worse at the right L4-L5 level where there is mild to moderate stenosis. There is also multilevel facet arthropathy, worst at the L5-S1 level.
