Lumbago with sciatica, unspecified side. Low back pain. Evaluate for stenosis. 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.Minimal 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: No significant disc disease. No spinal canal or neural foraminal stenosis.L5-S1: There is disc desiccation with a right paracentral annular fissure and small protrusion. There is contact of the right S1 nerve root without clear impingement. There is no significant central canal or neural foraminal stenosis. There is mild bilateral facet arthropathy.Paraspinous soft tissues are within normal limits.
1. Mild degenerative changes in the lumbar spine at the L5-S1 level. There is a small disc protrusion with contact of the right S1 nerve root in the lateral recess. There is otherwise no significant central canal stenosis or neural foraminal stenosis at any level in the lumbar spine.2. Mild facet arthropathy L5-S1 which may also be contributing to patient's low back pain.
