Female, 41 years old, with L5-S1 herniated nucleus pulposus. Assess preoperative change and morphology. Loss of disc height and T2 signal is seen at L5-S1. The previously demonstrated right foraminal disc extrusion with extension superiorly into the right lateral recess has significantly diminished in size with only trace residual herniated disc material. There is mild disc bulging at this level but without significant spinal canal or foraminal stenosis.The remaining intervertebral discs are preserved with no areas of significant spinal canal or foraminal stenosis. Facet arthropathy is seen at L4-5 and L5-S1. Spinal alignment is anatomic. Vertebral body height and morphology are within normal limits. No evidence of marrow replacement or marrow edema is seen. The visualized distal spinal cord, conus and nerve roots of the cauda equina are within normal limits. No epidural abnormalities are suspected.
Interval significant decrease in the size of a right foraminal/lateral recess disc extrusion at L5-S1.
