Sonographic features in 12 cases of proven cholangiocarcinoma were analyzed and correlated with findings on direct cholangiography. Proximal bile duct dilation was present in all cases of cholangiocarcinoma of the intrahepatic ducts except one. A neoplastic bile duct segment was detected in nine of the 12 cases. The neoplasms were seen as narrowed, normal-sized, or enlarged ducts, and contained intraluminal soft-tissue echoes or echogenic bands across the lumens. The sonographic accuracy was greater for lesions involving the bifurcation and the common hepatic duct than for common bile duct lesions. Cholangiography was superior to sonography in determining the length of the involved segment, whereas sonography was superior in detecting hepatic invasion and lymphadenopathy.
分析了12例经证实的胆管癌的超声特征，并与直接胆管造影的结果进行了关联。除1例肝内胆管癌外，其余所有病例均存在近端胆管扩张。12例中有9例检测到肿瘤性胆管节段。肿瘤表现为狭窄、正常大小或扩张的胆管，管腔内可见软组织回声或横跨管腔的强回声带。超声对累及肝门和肝总管病变的诊断准确性高于胆总管病变。在确定受累节段的长度方面，胆管造影优于超声，而在检测肝侵犯和淋巴结病方面，超声更具优势。
