摘要
报告近１２年来３９例肝内胆管细胞癌的超声检查结果，全部病例经手术或活检病理证实，其声像图分为局限型３１例，胆管型４例，囊肿型３例，１例超声漏诊。肝胆管癌声像图缺乏肝细胞癌的特征性表现，常常呈强回声，边界不清，外形不规则，较少出现低回声晕征。作者依不同分型分别予声像图分析。占位远端小胆管扩张是发现肿瘤的重要继发征象。彩超常不能发现动脉血供。积极开展超声引导穿刺活检有助于提高肝胆管癌的超声诊断水平。
The sonography of thiry-nine cases of intrahepatic cholangiocarcinoma (IHCC) in recent twelve years were reviewed. The diagnosis was proved pathologically. The tumor had three sonographic patterns, including thirty-one cases of focalized form, four cases of cholangial form and three cases of cystic form. The diagnosis was missed by ultrasound examination in one case. Unlike HCC, IHCC had no characteristic sonographic features and usually appeared hyperechoic with indistinct margin, irregular shape and less common hypoechoic rim. The sonographies of different patterns were analyzed . An important secondary sign of IHCC was the dilation of small bile duct distal to the tumor. Color Doppler flow imaging usually revealed shortage of arterial blood flow. It is concluded that the biopsy under the guidance of ultrasound will help the diagnosis of IHCC.
