DJD, back pain. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is levocurvature of the lumbar spine without significant spondylolisthesis at any level. Bone marrow signal is benign. The conus medullaris is normal in position.There is prominent vacuum disc phenomena at the L1-L2 and L4-L5 levels which is new at L1-L2 since prior MRI from 2009 but was present on CT dated 7/17/2014. Additional details regarding multilevel degenerative changes as below:L1-L2: Prominent vacuum disc phenomena. There is mild disc bulge, ligamentum flavum thickening, and bilateral facet arthropathy. There is fairly mild spinal canal stenosis. There is moderate bilateral left greater than right neural foraminal stenosis.L2-L3: Minimal disc bulge and mild facet arthropathy contribute to mild right neural foraminal narrowing. No significant spinal canal or left neural foraminal stenosis.L3-L4: Minimal disc bulge, bilateral facet arthropathy, and ligamentum flavum thickening contribute to minimal spinal canal stenosis. There is mild bilateral neural foraminal stenosis.L4-L5: Moderate to severe disc height loss and vacuum phenomena as well as bilateral ligamentum flavum thickening and moderate bilateral facet arthropathy. There is associated moderate to severe spinal canal stenosis. There is severe right and moderate left neural foraminal stenosis. These findings are minimally worse since 1/23/2009.L5-S1: Disc height loss with vacuum phenomena and small central disc extrusion. Advanced bilateral facet arthropathy. There is no significant spinal canal stenosis. There is mild to moderate bilateral neural foraminal stenosis. These findings have progressed since prior MRI from 1/23/2009.
1. Multilevel degenerative changes in the lumbar spine which have progressed since prior MRI from 1/23/2009. Findings are worst at the L4-L5 level where there is moderate to severe degree of spinal canal stenosis, severe right neural foraminal stenosis, and moderate left neural foraminal stenosis.2. Facet arthropathy throughout the lumbar spine, worst at the L4-L5 and L5-S1 levels. Additional details as above.
