Male, 64 years old, lumbar spinal pain. Trace retrolisthesis of L5 relative to S1 is seen. Spinal alignment is otherwise unremarkable.Vertebral body height and morphology are within normal limits accounting for scattered Schmorl's node deformities. Mild endplate edema is seen at L5-S1 without significant interval change.The distal spinal cord, conus and nerve roots of the cauda equina are unremarkable. No epidural abnormalities are suspected.L1-2: Unremarkable. L2-3: Mild facet hypertrophy and ligamentum flavum thickening. Loss of disc height and mild disc bulging. No significant spinal canal stenosis. Mild left foraminal narrowing. No interval changes. L3-4: Mild facet hypertrophy and ligamentum flavum thickening. Disc desiccation and mild disc bulging. No significant spinal canal stenosis. Moderate left and mild right foraminal narrowing. No interval changes. L4-5: Advanced facet arthropathy and ligamentum flavum thickening. Mild disc bulging. In combination with prominence of the dorsal epidural fat, this causes a mild narrowing of the thecal sac. Moderate bilateral foraminal narrowing. No interval changes. L5-S1: Mild facet hypertrophy and ligamentum flavum thickening. Loss of disc height and disc desiccation. Mild bulging disc. No significant spinal canal stenosis. Moderate left and mild right foraminal narrowing. No interval changes.
No significant interval change in the severity of disc and posterior element degeneration is seen. No high-grade spinal canal stenosis is detected. Scattered mild to moderate foraminal narrowing is also unchanged as discussed above.
