Objective To explore the characteristics of uhrasonography of hepatobiliary cystadenoma. Methods The ultrasonographic characteristics of 5 cases with hepatobiliary cystadenoma were retrospectively analysed, and compared with the operation and pathology. Results The ultrasonography of 5 cases was multilocular cystic mass,which seems to be,but not indeed communicating with the biliary tree,in which irregular septation was demonstrated in two-dimensional structure and also with perforator vessels along in color Doppler flow imagineg. And in some cases small papillary tuft and small loci of calcification was noted on the septation. Conclusions Muhilocular cystic mass,locating along the biliary tree, however not communicating with the the biliary tree, is an important diagnostic basis of biliary cystadenoma. And it should be distinguished with other cystic tumor in the liver.%目的 探讨肝内胆管性囊腺瘤的声像图特征.方法 对5例经手术病理证实的肝内胆管性囊腺瘤二维声像图及彩色多普勒特征进行回顾性分析.结果 5例肝内胆管性囊腺瘤的二维声像图均呈境界清楚的多房囊性肿块,肿块与胆管关系密切但无相通,囊内分隔带厚薄不均匀、分布不规则,部分分隔带上可见乳头状突起和微钙化,彩色多普勒超声显示分隔带内可见小血管走行.结论 沿肝内胆管走行而不与之相通的多房囊性肿块是肝内胆管性囊腺瘤的一个有诊断意义的声像特征,并且应注意与其他肝内囊性肿块的鉴别诊断.
