Pain and altered sensation. Five lumbar type vertebral bodies are present. Vertebral body heights are within normal limits. Alignment is within normal limits. Bone marrow signal is benign. There is disc desiccation at L3-4 and L4-5. 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.L3-L4: There is a left disc protrusion, with moderate left neuroforaminal stenosis. There is no spinal canal or right neural foraminal stenosis.L4-L5: There is an annular tear at L4-5 associated with a small central disc protrusion resulting in mild central canal as well as lateral recess narrowing. There is no neuroforaminal stenosis.L5-S1: No significant disc disease. No spinal canal or neural foraminal stenosis.Paraspinous soft tissues are within normal limits.
Multilevel degenerative disc disease most significant at L3-4 and L4-5. There is moderate left neural foraminal stenosis at L3-4 and mild central canal/lateral recess stenosis at L4-5.
