Cholangiolocellular carcinoma is a minor primary cancerous tumor of the liver and its coexistence with intrahepatic cholangiocarcinoma in the liver is rare. We herein report a case of concurrent cholangiolocellular carcinoma and intrahepatic cholangiocarcinoma in the liver, in addition to a rectal G1 neuroendocrine tumor, a so-called carcinoid. The intrahepatic tumors showed a different uptake in the F-fluoro-2-deoxyglucose (FDG) positron-emission tomography (PET)/computed tomography (CT) findings. In addition to conventional dynamic contrast-enhanced CT, we concluded that FDG PET/CT could therefore be a helpful modality to identify the properties of both cholangiolocellular carcinoma and intrahepatic cholangiocarcinoma.
肝内胆管细胞癌是肝脏的一种少见原发性癌性肿瘤，它与肝内胆管癌并存的情况较为罕见。我们在此报告一例肝脏同时存在肝内胆管细胞癌和肝内胆管癌，此外还伴有直肠G1神经内分泌肿瘤（即所谓的类癌）的病例。肝内肿瘤在F-氟代脱氧葡萄糖（FDG）正电子发射断层扫描（PET）/计算机断层扫描（CT）检查结果中显示出不同的摄取情况。除了传统的动态对比增强CT外，我们得出结论，FDG PET/CT因此可能是一种有助于鉴别肝内胆管细胞癌和肝内胆管癌特性的检查方法。
