摘　　要：目的:探讨分析肝胆管囊腺瘤的CT、MRCP及超声的影像学特点及其诊断价值。方法:回顾性分析5例手术病理证实的肝胆管囊腺瘤的CT、MRCP及超声表现。结果:5例肝胆管囊腺瘤,CT显示5例均为肝内囊实性病灶,边界清楚,增强扫描动脉期实质部分及囊壁轻度强化,门脉期进一步强化与肝实质接近;MRCP显示4例病灶为多分隔、分叶状,1例无明显分叶,囊性病灶表现为云絮状稍高信号;超声显示4例病灶为多发分隔、壁厚,1例囊壁可见多发高回声团。5例在三种影像学检查中均显示肝内胆管扩张,病灶与肝内胆管相通。结论:多种影像学检查方法联合应用有利于肝胆管囊腺瘤的诊断。Objective：To investigate imaging appearances of hepatobiliary cystadenoma,including CT,MRCP and ultrasonographic features.Methods：We retrospectively reviewed the radiological features of five patients with pathologically proven hepatobiliary cystadenoma.Results：All 5 patients with proven biliary cystadenoma appeared as a mixed cystic-solid lesion with clear boundary in the liver on CT.The lesion showed mild enhancement of solid component and cystic wall in the arterial phase,with further enhancement like the live during portal phase.MRCP showed a number of multilocular lesions with multiple septations in 4 cases and solitary lesion without loculation in 1 case.Biliary cystadenoma with protein within the locules had areas of relatively higher signal intensity on T1W1 and T2WI.Ultrasonography showed a number of lesions with multiple septations and wall thickening in 4 cases and multiple hyperechogenic interfaces with a cystic mass in 1 case.CT,MRCP and ultrasonography demonstrated dilatation of intrahepatic bile duct and the tumor communicated with the biliary tract in all the patients.Conclusion：Understanding the characteristic appearances of biliary cystadenoma at multiple imaging modalities can facilitate diagnosis.
