Female, 63 years old, status post tumor resection. Expected postoperative findings are seen compatible with recent T12-L1 laminectomy. A small amount of fluid is present within the laminectomy bed extending up to the level of the duraplasty which does appear to be intact.The previously seen intradural tumor at the L1 level has been resected with no evidence of any residual tumor. Prior mass effect upon the conus has been relieved.Spinal alignment is anatomic. Vertebral body height and morphology are unremarkable. No concerning marrow replacement or marrow signal abnormality is detected.Apart from some slight clumping of the cauda equina at the level of the resected tumor, the visualized intradural elements are unremarkable.Facet hypertrophy develops at lower lumbar levels becoming quite severe at L4-5.At L1-2 through L3-4, only minimal disc bulging is seen with no significant spinal canal or neuroforaminal stenosis.At L4-5, there is mild disc bulging but no significant spinal canal or neuroforaminal stenosis.At L5-S1, there is severe disc degeneration with complete loss of disc height and fatty endplate signal alteration. No significant spinal canal stenosis is seen. However, the left neural foramen is severely narrowed.
