 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 heterogenous but benign. The conus medullaris is normal in position.Mild 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: Minimal disc bulge. No spinal canal or neural foraminal stenosis.L4-L5: Right paracentral disc protrusion with effacement of the lateral recess and possible impingement of the traversing L5 nerve root. There is also mild to moderate central canal stenosis related to epidural fat and ligamentum flavum thickening and facet arthropathy. No significant neural foraminal stenosis.L5-S1: Left paracentral disc protrusion with effacement of the left lateral recess and possible impingement of the traversing left S1 nerve root. No significant central canal or neural foraminal stenosis.Mild facet arthropathy in the lower lumbar spine. Visualized sacroiliac joints are unremarkable. Paraspinous soft tissues are within normal limits.
1. Degenerative changes with right paracentral disc protrusion at L4-5 and left paracentral disc protrusion at L5-S1. There is associated narrowing of the lateral recesses which may be impinging on the traversing right L5 and left S1 nerve roots, respectively. 2. Mild to moderate central canal stenosis at L4-5.
