Bilateral thigh pain and numbness. Evaluate for disc disease. 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 benign. The conus medullaris is normal in position.Mild disc bulges at the lower thoracic spine at T10-T11 and T11-T12. There is mild prominence of the dorsal epidural fat. Multilevel degenerative changes are seen in the lumbar spine, 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: No significant disc disease. No spinal canal or neural foraminal stenosis.L4-L5: There is mild disc desiccation, ligamentum flavum thickening, and moderate bilateral facet arthropathy, which contribute to minimal central canal stenosis. Neural foramina are patent. There is a tiny synovial cyst posterior to the facet jointL5-S1: Moderate bilateral facet arthropathy. No spinal canal or neural foraminal stenosis.Paraspinous soft tissues are within normal limits. There is mild enhancement associated with the facet arthropathy, particularly at the L4-L5, and is likely on a degenerative basis. Otherwise no abnormal enhancement within the spine or paraspinous soft tissues is appreciated.
Degenerative changes in the lumbar spine with moderate facet arthropathy at the L4-L5 and L5-S1 levels. There is very mild narrowing of the spinal canal at the L4-L5 level. Spinal canal and neural foramina are otherwise patent.
