 There is minimal anterolisthesis of L3 on L4 and of L4 on L5. There is normal marrow signal in the vertebral bodies. The conus medullaris ends at the level of the upper L2. At the level of T11-T12 there is a loss of disc height with desiccation of the disc. There is also loss of normal disk signal and height in the mid to lower lumbar spine. Further details are provided below level by level.T12-L1: No evidence of disk bulge, neural foraminal narrowing or central stenosis.L1-L2: No evidence of disk bulge, neural foraminal narrowing or central stenosis.L2-L3: There is mild loss of disc height with desiccation. There is mild disc bulge with mild right and minimal left neural foraminal narrowing. No central canal stenosis.L3-L4: Mild diffuse disk bulge and ligamentum flavum thickening with facet degenerative changes causes mild to moderate bilateral neural foraminal narrowing and minimal spinal canal stenosis. L4-5: There is disc desiccation with loss of height. There is moderate degree of disc bulge, advanced facet arthropathy and ligamentum flavum thickening resulting in moderate degree of spinal stenosis similar to prior. There is bilateral moderate degree of neural foraminal stenosis, left more than the right. L5-S1: Minimal disk bulge with moderate facet degenerative changes and mild ligamentum flavum thickening without significant neural foraminal or central canal stenosis.
1. Degenerative changes as above, worst at the L4-5 level with moderate spinal canal and bilateral neural foraminal stenosis, not significantly changed since 6/17/2013. Mild L3-4 and L4-5 degenerative spondylolisthesis similar to prior.2. Advance facet arthropathy at L4-5 and to a lesser degree at L3-4 and L5-S1. These may be contributing to patient's back pain.
