Left leg pain and numbness to same pattern Five lumbar type vertebral bodies are presumed to be 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.Individual levels 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 a central and right foraminal disc protrusion. There is mild right neural foraminal stenosis where there is contact of the right L4 nerve root. No significant spinal canal or left neural foraminal stenosis.L5-S1: There is a large disc protrusion which is associated with effacement of the bilateral lateral recesses where there is mass effect on the descending S1 nerve roots. There is relatively mild central canal stenosis. There is also moderate left neural foraminal stenosis where there may be impingement of the left L5 nerve root. Minimal right neural foraminal narrowing.Paraspinous soft tissues are within normal limits.
Large disc protrusion at L5-S1 and small disc protrusion at L4-L5. There may be associated impingement of the nerve roots in the lateral recesses and neural foramina as detailed above.
