Female, 56 years old, with lower back pain and radicular symptoms in the right lower extremity. Within the limitations of mild motion degradation, the following observations are made.A trace retrolisthesis of L5 relative to S1 is seen, new from prior. Sagittal alignment is otherwise unremarkable. Vertebral body morphology and signal characteristics are within normal limits.The visualized distal spinal cord, conus and nerve roots of the cauda equina are within normal limits. No epidural abnormality is suspected.T12-L1: Unremarkable. L1-2: Mild loss of disc height and T2 signal. Minimal disc bulging. No significant spinal canal or foraminal stenosis. L2-3: Mild facet arthropathy. No significant spinal canal or foraminal stenosis. L3-4: Mild facet arthropathy. No significant spinal canal or foraminal stenosis.L4-5: Moderate facet arthropathy. Mild loss of disc height and T2 signal. Mild bulging disc slightly asymmetric to the right, similar to prior. No significant spinal canal or foraminal stenosis. L5-S1: Moderate facet arthropathy and ligamentum flavum thickening, mildly progressed. Loss of disc T2 signal and mild disc bulging, slightly progressed. No significant spinal canal stenosis. Mild right foraminal narrowing.
Mild interval progression of relatively mild degenerative findings is seen. No areas of high-grade spinal canal or neuroforaminal stenosis are detected.
