Cholangiocarcinoma is the second most common primary hepatic malignant tumor after hepatocellular carcinoma, accounting for 5-30% of all primary hepatic malignant tumors [1]. Intrahepatic cholangiocarcinomas can be classified as peripheral cholangiocarcinoma, which originates from an interlobular biliary duct, or as hilar cholangiocarcinoma, which originates from a main hepatic duct or from the bifurcation of the common hepatic duct. Intrahepatic cholangiocarcinomas account for only about half of cholangiocarcinomas, and this pictorial essay focuses only on the peripheral form of the disease. Clinically, therapeutically, and radiologically, these two types of cholangiocarcinomas differ. Features suggestive of the diagnosis of peripheral cholangiocarcinoma can be shown by sonography, CT, and MR imaging. Cholangiography and angiography have a limited role in evaluating this neoplasm that manifests as a focal mass. This essay reviews the appearances of peripheral cholangiocarcinoma and discusses the various imaging techniques that can be used to evaluate this unusual tumor that is often resectable and potentially curable.
胆管癌是继肝细胞癌之后第二常见的原发性肝脏恶性肿瘤，占所有原发性肝脏恶性肿瘤的5% - 30%[1]。肝内胆管癌可分为起源于小叶间胆管的周围型胆管癌，或起源于肝总管或肝总管分叉处的肝门部胆管癌。肝内胆管癌仅占胆管癌的约一半，本文仅聚焦于该疾病的周围型。在临床、治疗和放射学方面，这两种类型的胆管癌有所不同。超声、CT和磁共振成像（MR成像）可显示提示周围型胆管癌诊断的特征。胆管造影和血管造影在评估这种表现为局灶性肿块的肿瘤方面作用有限。本文回顾了周围型胆管癌的表现，并讨论了可用于评估这种通常可切除且有可能治愈的罕见肿瘤的各种成像技术。
