Cholangiolocellular carcinoma (CoCC) is a rare primary liver cancer. It is considered to originate from hepatic progenitor or stem cells. We report a rare case of a 74-year-old male with CoCC of the liver and duodenal gastrointestinal stromal tumor (GIST). Both tumors manifested tracer uptakes on F-18 fluorodeoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT); however, the uptake in hepatic tumor was extremely higher than that in the duodenal tumor. This finding was helpful to exclude the metastasis of GIST.
胆管细胞癌（CoCC）是一种罕见的原发性肝癌。它被认为起源于肝祖细胞或干细胞。我们报告了一例罕见病例，一名74岁男性患有肝脏胆管细胞癌和十二指肠胃肠道间质瘤（GIST）。两种肿瘤在F-18氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描（F-18 FDG PET/CT）上均表现出示踪剂摄取；然而，肝脏肿瘤的摄取明显高于十二指肠肿瘤。这一发现有助于排除胃肠道间质瘤的转移。
