72-year-old woman with history of right radicular leg pain. Five lumbar type vertebral bodies are present on this study. The vertebral body heights are within normal limits. There is slight exaggeration of the lumbar lordosis which may be positional. Lumbar spinal alignment is otherwise normal. Small, scattered foci of T1 and T2 hyperintensity may represent hemangiomata or areas of focal fat. The bone marrow signal is benign. The conus medullaris is normal in position.There is mildly increased signal in all of the intervertebral discs suggesting desiccation. 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 minimal disc bulge, eccentric to the right. Additionally, there is mild ligamentum flavum thickening. Minimal right neural foraminal narrowing. There is no spinal canal or left neural foraminal stenosis.L4-L5: There is a mild bulge, eccentric to the right. A small focus of increased T2 signal suggests a mild posterior annular fissure on the right. Additionally, there is mild bilateral facet arthropathy with ligamentum flavum thickening. There is mild effacement of the right lateral recess with minimal contact with the L5 descending nerve but no evidence of impingement. Minimal right neural foraminal narrowing also without clear evidence of impingement. There is no spinal canal or left neural foraminal stenosis.L5-S1: There is a mild bulge, eccentric to the right. Additionally, there is mild bilateral facet arthropathy with ligamentum flavum thickening. There is no spinal canal or neural foraminal stenosis.Small bilateral cystic lesions at the S1 level are compatible with perineural cysts.The paraspinous soft tissues are within normal limits.
Mild multilevel degenerative changes without spinal canal stenosis or clear evidence of nerve root impingement. Please see comments above.
