Low back pain Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is minimal retrolisthesis of L4 and L5 and some straightening involving the lumbar lordotic curvature. Alignment is otherwise maintained. Bone marrow signal is benign. The conus medullaris is normal in position.There is developmental narrowing of the mid to lower lumbar spinal canal with superimposed degenerative changes 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 disc desiccation with minimal disc bulge. Mild facet arthropathy with distention of the facet joints. There is no significant spinal canal stenosis. There is mild bilateral neural foraminal stenosis. L4-L5: There is disc desiccation with mild disc bulge and dorsal annular fissure. There is also mild facet arthropathy with distention of the facet joints. Mild narrowing of the spinal canal which is predominantly on a developmental basis and in part related to minimal retrolisthesis and disc bulge. Minimal narrowing of the bilateral neural foramina.L5-S1: No significant disc disease. No spinal canal or neural foraminal stenosis. Mild facet arthropathy with mild distention of the facet joints.Paraspinous soft tissues are within normal limits. Left renal cysts incidentally noted.
Mild developmental narrowing of the lumbar spinal canal with superimposed mild degenerative changes including small disc bulges at the L3-L4 and L4-L5 levels. There is mild bilateral L3-L4 and minimal L4-L5 neural foraminal stenosis. There is also mild facet arthropathy with distention of the facet joints from L3-L4 to L5-S1 which may be contributing to patient's low back pain.
