Lumbar radiculopathy, claudication. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is minimal anterolisthesis of L3 on L4 and minimal retrolisthesis of L4 and L5 which appear new since prior. Alignment is otherwise maintained. Multilevel degenerative changes are present with multilevel disc desiccation, progressed particularly at the L4-L5 level with also new endplate edematous marrow signal changes at the L4-L5 level. Bone marrow signal is benign. The conus medullaris is normal in position at the L1-L2 level.Multilevel degenerative changes are seen, as described below:T12-L1: Severe disc height loss with disc osteophyte complex. There is effacement of the ventral thecal sac, right greater than left. There is also bilateral facet arthropathy. There is overall mild to moderate spinal canal stenosis. There is mild to moderate right and mild left neural foraminal narrowing. These findings have progressed.L1-L2: Minimal disc bulge and advanced bilateral facet arthropathy with moderate spinal canal stenosis which has progressed in the interval. There is mild narrowing of the bilateral neural foramina.L2-L3: Mild disc bulge, advanced facet arthropathy, and ligamentum flavum thickening are again seen with moderate to severe spinal canal stenosis similar to prior. There is mild narrowing of the neural foramina.L3-L4: There is severe bilateral facet arthropathy and ligamentum flavum thickening as well as minimal disc bulge. There is moderate to severe spinal canal stenosis which is slightly progressed in the interval. Minimal narrowing of the neural foramina.L4-L5: Disc bulge and bilateral facet arthropathy. There is partial effacement of the lateral recesses. No significant central spinal canal stenosis. There is mild right and minimal left neural foraminal narrowing.L5-S1: Thecal sac terminates at this level with epidural fat again evident, likely developmental. There is bilateral facet arthropathy, more advanced on the right and progressed in the interval. There is mild to moderate right and mild left neural foraminal stenosis.
Multilevel degenerative changes throughout the lumbar spine which have progressed since prior MRI since 2/9/2011. There is moderate to severe spinal canal stenosis at L2-L3 and L3-L4 and to a lesser degree at the L1-L2 and T12-L1 levels. Multilevel neural foraminal stenoses and additional details as above.
