Here, we present a case of bilateral synchronous renal cell carcinoma in a 52-year-old male patient, who underwent fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-CT) scan followed by surgical removal of both tumors. On PET scan, left renal mass showed intense FDG uptake while uptake in the right renal mass was minimal. Histopathologically, both tumors were conventional clear cell carcinoma (Fuhrman Grade III). Only the FDG-avid tumor in the left kidney had lymphovascular invasion and necrosis, which are markers of aggressive form of any tumor. FDG PET-CT can act as strong and noninvasive prognostic parameter that could help to identify patients with aggressive disease before treatment.
在此，我们报告一例52岁男性双侧同步性肾细胞癌患者，该患者接受了氟脱氧葡萄糖正电子发射断层扫描-计算机断层扫描（FDG PET-CT）检查，随后手术切除了双侧肿瘤。在PET扫描中，左肾肿块显示出强烈的FDG摄取，而右肾肿块的摄取极少。组织病理学检查显示，两个肿瘤均为传统透明细胞癌（福尔曼三级）。只有左肾中FDG摄取活跃的肿瘤存在淋巴管侵犯和坏死，这些都是任何肿瘤侵袭性形式的标志物。FDG PET-CT可作为一种强大的非侵入性预后参数，有助于在治疗前识别侵袭性疾病患者。
