回顾性分析7例肝内胆管黏液性乳头状胆管细胞癌(intraductal papillary mucinous neoplasm of the intrahepatic bile ducts,IPMN-B)的临床资料,IPMN-B是临床上一种罕见的胆管恶性肿瘤,误诊率高,综合运用超声、电子计算机X线断层扫描(computed tomography,CT)、核磁共振成像(magnetic resonance imaging,MRI)及磁共振胰胆管造影(magnetic resonance cholangiopancreatography,MRCP)等检查方法可对疾病进行辅助诊断,在胆管内占位及胆管显著扩张的诊断中具有重要意义.
