Low back pain, radiating down left leg, some numbness Examination is mildly motion degraded. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is grade 1 anterolisthesis of L4 and L5 as seen on prior radiograph. Alignment is otherwise within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position.Multilevel degenerative changes are seen, as described below:L1-L2: Minimal disc bulge, ligamentum flavum thickening and mild facet arthropathy. No significant spinal canal or neural foraminal stenosis. L2-L3: Minimal disc bulge, ligamentum flavum thickening and mild facet arthropathy. No significant spinal canal or neural foraminal stenosis. L3-L4: Disc bulge eccentric to the right, ligamentum flavum thickening, and bilateral facet arthropathy. There is mild effacement of the lateral recesses and mild central spinal canal stenosis. There is mild bilateral neural foraminal stenosis, right worse than left. L4-L5: Advanced bilateral facet arthropathy and grade 1 anterolisthesis. There is also disc uncovering and minimal bulge. No significant central spinal canal stenosis. There is mild to moderate bilateral neural foraminal stenosis.L5-S1: There is a disc bulge with small central disc extrusion and moderate bilateral facet arthropathy. No significant central spinal canal stenosis. There is moderate right and moderate to severe left neural foraminal stenosis. There is enhancement associated with the facet arthropathy at the L3-L4 to L5-S1 levels. No suspicious enhancing lesions. Multiple bilateral renal cysts.
Multilevel degenerative changes in the lumbar spine including degenerative grade 1 anterolisthesis at L4-L5. There is mild central spinal canal stenosis at L3-L4. There is also multilevel neural foraminal stenosis worst at the left L5-S1 level where there may be impingement of the left L5 nerve root.
