A 23-year-old woman with recurrent uterine endometrial stromal sarcoma underwent FDG PET/CT, which showed pelvic recurrence and multiple pulmonary metastases. In addition, increased activity in a vertical soft tissue mass along the left ureter was noted, which appears similar to retroperitoneal fibrosis on PET/CT images. However, pathological examination demonstrated that the elevated FDG activity in this mass was a result of tumor thrombus from endometrial stromal sarcoma in the left ovarian arteries and veins.
一位 23 岁女性，因复发性子宫子宫内膜间质肉瘤行 FDG PET/CT 检查，显示盆腔复发和多个肺转移。此外，还注意到沿左侧输尿管的垂直软组织肿块活性增加，在 PET/CT 图像上类似于腹膜后纤维化。然而，病理检查显示该肿块中 FDG 活性升高是由于左卵巢动静脉中的子宫内膜间质肉瘤肿瘤血栓。
