Severe low back pain since one month, status post fall Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is mild retrolisthesis of L5 on S1. Alignment of the lumbar spine is otherwise maintained. Bone marrow signal is benign. The conus medullaris is normal in position. Multilevel degenerative changes are seen particularly at the L5-S1 level where there is severe disc height loss and vacuum phenomena.Additional details as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: Mild disc bulge. No significant spinal canal stenosis. Minimal narrowing of the neural foramina.L3-L4: Mild disc bulge and mild facet arthropathy. No significant spinal canal stenosis. There is mild right and no significant left neural foraminal stenosis.L4-L5: Mild disc bulge, facet arthropathy, ligamentum flavum thickening. No significant spinal canal stenosis. There is mild right and minimal left neural foraminal stenosis.L5-S1: Severe disc height loss, vacuum phenomena, and mild retrolisthesis. There is bilateral facet arthropathy. No significant spinal canal stenosis. There is mild to moderate right and mild left neural foraminal stenosis.Postgadolinium images demonstrate no abnormal enhancement. Paraspinous soft tissues are within normal limits.
Multilevel degenerative changes in the lumbar spine as detailed above, relatively worse at the L5-S1 level. No evidence of compression fracture.
