Low back pain, fatigue Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is grade 1 retrolisthesis of L2 on L3. Alignment is otherwise within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position.Multilevel degenerative changes are seen, with disc desiccation throughout the lumbar spine and multilevel loss of disc height, worst at the L5-S1 level. Individual levels as described below:L1-L2: Minimal disc bulge. No spinal canal or neural foraminal stenosis.L2-L3: Mild disc bulge eccentric to the right. There is mild effacement of the right lateral recess and mild right neural foraminal stenosis. No left neural foraminal stenosis. There is no significant central canal stenosis. L3-L4: Mild disc bulge, ligamentum flavum thickening and facet arthropathy. There is mild central canal stenosis and partial effacement of the bilateral lateral recesses. There is moderate right and minimal left neural foraminal stenosis. L4-L5: Mild disc bulge, ligamentum flavum thickening and facet arthropathy. No significant spinal canal stenosis. There is no significant right and mild to moderate left neural foraminal stenosis. L5-S1: Minimal disc bulge, eccentric to the left. No spinal canal stenosis. There is up to moderate bilateral neural foraminal stenosis. Paraspinous soft tissues are within normal limits.
Mild to moderate degenerative changes in the lumbar spine. There is mild spinal canal stenosis at the L3-L4 level; otherwise no high-grade spinal canal stenosis at any level. There is varying degrees of mild to moderate neural foraminal stenosis as detailed above.
