Pain and weakness with ambulation. Rule out arthritic changes or disc herniation. 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 low T1 and low T2 signal at the right S1 level may represent a bone island. Marrow signal changes at the L3-L4 to L5-S1 endplates are on a degenerative basis. The conus medullaris is normal in position.Multilevel degenerative changes are seen, as described below:L1-L2: Minimal disc bulge and mild facet arthropathy. No spinal canal or neural foraminal stenosis.L2-L3: Mild disc bulge and bilateral facet arthropathy. No spinal canal or neural foraminal stenosis.L3-L4: Loss of disc height with edema involving the disc and adjacent endplates which is probably on a degenerative basis. There is a disc bulge with partial effacement of the lateral recesses. Mild facet arthropathy. There is moderate to severe left and mild to moderate right neural foraminal stenosis.L4-L5: Disc bulge eccentric to the right and bilateral facet arthropathy. No significant central spinal canal stenosis. Partial effacement of the right lateral recess. There is moderate right neural foraminal stenosis and mild left neural foraminal stenosis.L5-S1: Disc bulge and moderate bilateral facet arthropathy. No significant spinal canal stenosis. There is mild to moderate right and moderate to severe left neural foraminal stenosis.Paraspinous soft tissues are within normal limits.
1. Multilevel degenerative changes in the lumbar spine. There is no significant central spinal canal stenosis at any level. Neural foraminal stenoses from L3-L4 to L5-S1 as detailed above.2. There is edema at the L3-L4 disc space and adjacent endplates which is likely on a degenerative basis.
