Radicular left leg pain and urinary retention 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. Focus of T1 hyperintensity within the L5 vertebral body is compatible with small hemangioma or focus of fat. No suspicious osseous lesions. 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: Minimal disc bulge, ligamentum flavum thickening, and facet arthropathy. No significant spinal canal stenosis. There is minimal bilateral neural foraminal narrowing.L4-L5: Disc desiccation with disc bulge, moderate bilateral facet arthropathy, and ligamentum flavum thickening result in mild spinal canal stenosis. There is mild effacement of the lateral recesses, left greater than right, which may be affecting the left descending L5 nerve root. There is also mild bilateral neural foraminal stenosis, left relatively greater than right. L5-S1: There is disc desiccation with mild height loss. There is also a disc bulge which contributes to mild effacement of the lateral recesses. No significant central canal stenosis. There is moderate bilateral facet arthropathy and ligamentum flavum thickening. There is moderate bilateral neural foraminal stenosis which may be affecting the exiting L5 nerve roots.Paraspinous soft tissues are within normal limits.
1. Degenerative changes in the lumbar spine at the L4-L5 and L5-S1 levels. There is moderate bilateral neural foraminal stenosis at the L5-S1 levels where there may be impingement of the exiting L5 nerve roots. 2. Mild central spinal canal stenosis at the L4-L5 level. No high-grade spinal canal stenosis at any level. Please see additional details above.
