Low back pain after lifting heavy object with radiation down the right leg. History of MS, lumbar discectomy in 2009. 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.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: There is a new right foraminal disc extrusion with mild cranial migration. There is moderate degree of right-sided neural foraminal stenosis and suspected impingement of the right exiting L3 nerve root. No significant spinal canal or left neural foraminal stenosis.L4-L5: Small right foraminal disc protrusion is also new since prior and contacts the right L4 nerve root. There is mild right-sided neural foraminal stenosis. Minimal left neural foraminal narrowing. No significant spinal canal stenosis.L5-S1: Prior right-sided laminotomy. There is a dorsal annular fissure and right paracentral protrusion. Minimal right neural foraminal stenosis. No significant spinal canal stenosis or left neural foraminal stenosis. There is bilateral facet arthropathy.
1. New right foraminal disc extrusion at the L3-L4 level where there may be impingement of the right L3 nerve root.2. Smaller, new right foraminal disc protrusion at the L4-L5 level which contacts the right L4 nerve root.3. Postoperative changes related to remote right L5-S1 discectomy.
