 Motion degrades sensitivity. For the purpose of this study the most inferior level is defined as L5-S1. The vertebral column alignment is within normal limits. The vertebral body heights are preserved. The vertebral bone marrow signal is unremarkable. The spinal cord terminates at the T12 inferior endplate and displays normal signal and morphology. Atrophy of the lower lumbar paraspinal musculature noted. Partially imaged left renal cysts.Multilevel degenerative changes are seen, as describe below:T12-L1, L1-L2: No significant spinal canal or foraminal stenosis.L2-3: Minimal disc bulging with mild bilateral facet arthropathy. No significant spinal canal or foraminal stenosis.L3-4: Disc bulge and bilateral facet arthropathy as well as prominence of the dorsal epidural fat contribute to mild to moderate spinal canal stenosis, slightly worse since prior exam. There is mild bilateral neural foraminal stenosis, not significantly changed from prior exam. Widening of the facet joints again noted. L4-5: Post-surgical changes of a remote laminectomy with areas of osseous fusion involving the posterior elements from L4-S1. No evidence of significant central or neural foraminal stenosis.L5-S1: No significant spinal canal stenosis. Minimal narrowing of the neural foramina. Prior right-sided laminectomy.
1. Post-surgical changes in the lumbar spine with laminectomies at L4-L5 and L5-S1 and solid osseous fusion involving the posterior elements from L4 through S1 better seen on prior CT. 2. Mild to moderate spinal canal stenosis at L3-4, which appears slightly worse since prior exam from 9/5/2012. 3. Mild L3-L4 and minimal L5-S1 bilateral neural foraminal narrowing. Neural foramina are otherwise patent.
