A 69-year-old woman was diagnosed with stage IIIA advanced Type IV Klatskin cholangiocarcinoma, which was treated with radical choledochectomy, extended right hepatectomy and left hepaticojejunostomy. About six months after surgery, she presented with painless jaundice. A 2-18F-fluoro-2-deoxy-D-glucose positron emission tomography-computed tomography (F18-FDG PET-CT) was performed, which detected an FDG-avid umbilical metastatic nodule. We describe the F18-FDG PET-CT features of umbilical metastatic nodule in recurrent cholangiocarcinoma. It is sometimes difficult to detect the lesions when they present with non-specific soft tissue thickening on routine CT imaging. F18-FDG PET-CT would probably render these lesions easier to detect and interpret.
一位 69 岁女性被诊断为 IIIA 期 IV 型 Klatskin 胆管癌，接受了根治性胆管切除术、扩大右半肝切除术和左肝空肠吻合术。术后约 6 个月，她出现无痛性黄疸。进行了 2-18F-氟-2-脱氧-D-葡萄糖正电子发射断层扫描-计算机断层扫描（F18-FDG PET-CT），检测到 FDG 摄取的脐转移性结节。我们描述了复发性胆管癌中脐转移性结节的 F18-FDG PET-CT 特征。当它们在常规 CT 成像上表现为非特异性软组织增厚时，有时很难检测到病变。F18-FDG PET-CT 可能会使这些病变更容易检测和解释。
