68-year-old woman with history of lumbago, sciatica, and right leg pain Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is minimal retrolisthesis of L5 on S1, otherwise alignment is within normal limits. Probable hemangiomata in L1 and L2 vertebral bodies. Bone marrow signal is benign. The L4/L5 and L5/S1 discs have decreased T2 signal suggesting desiccation. The conus medullaris is normal in position.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: There is a mild disc bulge. There is moderate bilateral facet arthropathy with ligamentum flavum thickening. Bilateral neural foramina and the spinal canal are mildly narrowed.L4-L5: There is a mild disc bulge. There is moderate to severe bilateral facet arthropathy with ligamentum flavum thickening. Bilateral neural foramina and the spinal canal are also mildly narrowed.L5-S1: There is a mild disc bulge, slightly eccentric to the left. There is moderate bilateral facet arthropathy. The left lateral recess is slightly narrowed, similar to the prior examination. There is mild narrowing of the left neural foramen. The right neural foramen and central spinal canal are without significant stenosisParaspinous soft tissues are within normal limits.
1. No significant change in mild multilevel degenerative changes in the lumbar spine. No high-grade spinal canal or high-grade neural foraminal stenosis. Additional details as above.2. There is multilevel facet arthropathy in the lower lumbar spine, relatively worse at the L4-5 level, which may be contributing to patient's low back pain.
