52-year-old man with history of low back pain. Five lumbar type vertebral bodies are present on this study. The vertebral body heights are within normal limits. There is normal lumbar lordosis. Small, scattered foci of T1 and T2 hyperintensity likely represent hemangiomata and the bone marrow signal is benign. The conus medullaris is normal in position.There is mildly decreased signal in the L3/L4 and L4/L5 discs suggesting desiccation. Throughout the lumbar spine, there is developmental narrowing of the spinal canal. Additional multilevel degenerative changes are seen, as described below:L1-L2: There is no significant disc disease. There is no spinal canal or neural foraminal stenosis.L2-L3: There is no significant disc disease. There is no spinal canal or neural foraminal stenosis.L3-L4: There is mild disc bulge along with mild facet arthropathy and ligamentum flavum thickening. There is mild to moderate left neural foraminal stenosis with mild right neural foraminal stenosis. There is mild spinal canal stenosis, mostly due to developmentally narrow canal.L4-L5: There is a mild bulge along with moderate facet arthropathy and ligamentum flavum thickening. There is moderate to severe right neural foraminal stenosis with mild to moderate left neural foraminal stenosis. There is mild to moderate spinal canal stenosis, mostly due to developmentally narrow canal.L5-S1: There is a minimal disc bulge and mild bilateral facet arthropathy. There is mild right neural foraminal stenosis and minimal left neural foraminal stenosis. There is no spinal canal stenosis.The paraspinous soft tissues are within normal limits.
1.Multilevel degenerative changes in the lumbar spine along with a developmentally narrow spinal canal which results in stenosis which is, at worst, mild to moderate at L4/L5. No high-grade spinal canal stenosis.2.Multilevel neural foraminal stenoses as detailed above.3.Facet arthropathy at L3/L4, L4/L5, and L5/S1, which may also be contributing to the low back pain.
