Low back pain worse with erect spine and generalized leg weakness with walking Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is trace anterolisthesis of L5 on S1. Alignment is otherwise within normal limits. There is mild nonspecific heterogeneity of the bone marrow without destructive lesions. The conus medullaris is normal in position.Multilevel degenerative changes are seen. There is disc height loss at all levels, relatively worse at the L5-S1 level where there is also vacuum phenomena. Small Schmorl's nodes are also evident involving the endplates. Edematous marrow signal changes are noted at the inferior endplate of L4 level. Individual levels as below:L1-L2: No spinal canal or neural foraminal stenosis. Mild facet arthropathy.L2-L3: Mild disc bulge and endplate osteophytes. Mild facet arthropathy. No spinal canal stenosis. Mild left neural foraminal narrowing. Minimal right neural foraminal narrowing.L3-L4: Mild disc bulge and endplate osteophytes. Mild facet arthropathy. There is no spinal canal stenosis. Minimal left neural foraminal narrowing. No right neural foraminal stenosis.L4-L5: Minimal disc bulge. Bilateral facet arthropathy. No spinal canal stenosis. Minimal narrowing of the neural foramina. L5-S1: Mild retrolisthesis and disc bulge. There is no spinal canal stenosis. Mild facet arthropathy. There is mild narrowing of the bilateral neural foramina. Paraspinous soft tissues are within normal limits.
Degenerative changes throughout the lumbar spine without spinal canal stenosis at any level. There is fairly mild narrowing of the neural foramina at multiple levels as described above. There is generalized facet arthropathy throughout the lumbar spine which may be contributing to patient's back pain.
