Biliary cystadenocarcinoma is rare biliary ductal neoplasm, usually occurring in middle-aged women, which arises in a healthy liver, with a better prognostic than other malignant tumors of the liver. We report a new case documented by echography, CT scan and MR. Echography showed multiple heterogeneous and septate masses with fluid-fluid level and dilatation of the intra-hepatic biliary ducts. CT showed multilocular cystic masses with internal septa and papillary excrescences showing contrast enhancement and no calcification. MR displayed a rather intense and variable signal in some parts of the masses on T1 weighted images, flasching on T2 weighted images, corresponding to a hemorrhagic fluid, confirmed by surgery. On T1 weighted images after gadolinium administration, the masses were less well visualized.
胆管囊腺癌是一种罕见的胆管肿瘤，通常发生于中年女性，起源于正常肝脏，预后较其他肝脏恶性肿瘤好。我们报告1例经超声、CT扫描及磁共振成像（MR）确诊的新病例。超声显示多个不均质、有分隔的肿块，有液-液平面，肝内胆管扩张。CT显示多房囊性肿块，内有分隔及乳头状突起，有强化，无钙化。MR显示肿块在T1加权像上部分区域信号较强且多变，在T2加权像上呈高信号，提示为出血性液体，手术证实。钆剂增强后T1加权像上肿块显示欠清。
