Right lower extremity pain/numbness/coarse tremor. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is minimal retrolisthesis of L4 on L5. Alignment is otherwise within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position.Mild 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.L3-L4: No significant disc disease. No spinal canal or neural foraminal stenosis.L4-L5: There is disc desiccation with disc bulge and a small central disc protrusion. There is no significant spinal canal stenosis. There is minimal asymmetric narrowing of the right neural foramen. There is otherwise no significant spinal canal or neural foraminal stenosis.L5-S1: No significant disc disease. No spinal canal or neural foraminal stenosis.Paraspinous soft tissues are within normal limits.
At L4-L5, there is a disc bulge and small central disc protrusion, minimally asymmetrically greater on the right. There is no significant spinal canal or neural foraminal stenosis at any level in the lumbar spine.
