摘要

一名 75 岁的男性头颈部鳞状细胞癌患者接受了 f-18- 氟脱氧葡萄糖（18F-FDG）正电子发射计算机断层扫描（PET/CT）分期扫描，结果显示右肝叶有额外的灶性异常摄取。患者接受了可能的转移性疾病治疗。重新分期的 FDG PET/CT 扫描显示头颈部的摄取已经消失，而假定的肝转移灶仍有灶性摄取。静脉注射造影剂的腹部 CT 显示胆囊内有一个增强的肿块，但没有扩展到肝脏。胆囊切除术发现胆囊内乳头状肿瘤。最初出现的肝转移是由于错误定位造成的。

FDG Avid Intracholecystic Papillary Neoplasm Mimicking Hepatic Metastasis in a Patient with Head-and-neck Cancer.

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.
