A 75-year-old male with head-and-neck squamous cell cancer received a staging f-18-fluorodeoxyglucose (18F-FDG) positron emission tomography-computed tomography (PET/CT) scan which showed additional focal abnormal uptake in the right hepatic lobe. The patient was treated for probable metastatic disease. Restaging FDG PET/CT scan revealed resolution of uptake in the head-and-neck and persistent focal uptake in the presumed liver metastasis. An abdominal CT with intravenous contrast revealed an enhancing mass in the gallbladder, without extension into the liver. Cholecystectomy revealed an intracholecystic papillary neoplasm of the gallbladder. The initial appearance of hepatic metastasis was due to a misregistration artifact.
一名75岁的头颈部鳞状细胞癌男性患者接受了分期的F-18-氟脱氧葡萄糖（18F-FDG）正电子发射断层扫描-计算机断层扫描（PET/CT），结果显示右肝叶有额外的局灶性异常摄取。该患者接受了可能的转移性疾病治疗。再次进行的FDG PET/CT扫描显示头颈部的摄取消失，而推测的肝转移灶仍有持续的局灶性摄取。静脉注射造影剂的腹部CT显示胆囊有一个强化肿块，未延伸至肝脏。胆囊切除术显示为胆囊内乳头状肿瘤。最初肝脏转移的表现是由于配准错误伪影所致。
