 There is transitional anatomy with lumbarization of S1. For the purposes of this exam, the last fully formed disc is at S1-S2.There are stable postoperative findings lung the lumbar region related to resection of a previous left paraspinal mass including resection of the left paraspinal musculature. There is persistent laxity of the left posterior abdominal wall with partial herniation of the left kidney. There is no mass-like enhancement within the surgical bed or within the spinal canal. The cauda equina remains along the right aspect of the spinal canal, likely secondary to the scoliosis, which has a leftward lumbar curvature and a rightward thoracic curvature. There is hypertrophy of the left lumbar posterior elements which is likely compensatory. The vertebral body heights are preserved. The vertebral bone marrow signal is unremarkable. There is no significant spinal canal stenosis. The spinal cord is of normal signal and caliber with the conus terminating at the T12 level. There is persistent multilevel left-sided foraminal narrowing along the lumbar spine secondary to the scoliosis.There is a large amount of fecal debris within the visualized colonic loops and rectum.
1. Continued stable appearance of post-operative findings without evidence of tumor recurrence.2. Chronic rotatory scoliosis and bulging of the left kidney at the surgical site, secondary to paraspinal muscle resection.
