Male, 46 years old, with chronic low back pain. Trace anterolisthesis of L4 relative to L5 is seen. Spinal alignment is otherwise unremarkable. Vertebral body height and morphology are within normal limits. No marrow edema or marrow replacement is suspected.The visualized distal spinal cord, conus and nerve roots of the cauda equina are within normal limits. No epidural abnormalities are suspected.L1-2: No significant spinal canal stenosis or neuroforaminal narrowing. L2-3: No significant spinal canal stenosis or neuroforaminal narrowing. L3-4: Mild facet arthropathy. No significant spinal canal stenosis or neuroforaminal narrowing. L4-5: Advanced facet arthropathy. Loss of disc height with mild disc bulging. Moderate generalized narrowing of the spinal canal. Mild bilateral foraminal narrowing. L5-S1: Mild facet arthropathy. Disc bulging with a superimposed central protrusion. No significant spinal canal or foraminal stenosis.
1.Disc degeneration at L4-5 results in a moderate spinal canal stenosis and mild narrowing of the neural foramina. 2.Disc degeneration is also seen at L5-S1, but without significant associated spinal canal or foraminal compromise.3.Advanced facet arthropathy is demonstrated at L4-5.
