Female, 54 years old, with spinal stenosis. Straightening of the lumbar lordosis is unchanged. At most there may be a trace retrolisthesis of L4 relative to L5. Alignment is otherwise unremarkable. Marrow signal characteristics are heterogeneous but overall benign in nature. Edematous endplate signal at L3-4 has slightly progressed.The distal spinal cord, conus and cauda equina are unremarkable. No epidural abnormalities are suspected.L1-2: Mild facet arthropathy. No significant spinal canal or foraminal stenosis. No interval changes. L2-3: Mild facet arthropathy. Mild bulging disc. Narrowing of the lateral recesses but no significant spinal canal stenosis. Minimal if any foraminal narrowing. No interval changes. L3-4: Moderate facet arthropathy. Slight loss of disc height and minimal disc bulging. New left far lateral annular fissuring and protrusion. No significant spinal canal stenosis. Mild bilateral foraminal narrowing, slightly progressed. L4-5: Moderate facet arthropathy. Loss of disc height with mild disc bulging. Mild spinal canal stenosis. Mild bilateral foraminal narrowing. No significant interval changes. L5-S1: Moderate facet arthropathy with effusions. Progressive ligamentum flavum thickening. Effacement of the posterior aspect of the thecal sac with mild generalized spinal canal narrowing. Moderate bilateral foraminal narrowing. Findings have progressed.
1.Progressive degenerative findings at L5-S1, particularly affecting the ligamentum flavum. As a result, there is progressive moderate bilateral foraminal narrowing.2.Degenerative findings at additional levels are stable or only mildly increased. No areas of high-grade spinal canal stenosis are seen.
