DIC-CT findings of biliary cystadenocarcinoma communicating with the bile duct: A case report

Among the intrahepatic cystic diseases except Caroli's disease, only biliar y cystadenoma/cystadenocarcinoma may communicate with the bile duct. We pre sent a case of biliary cystadenocarcinoma in which drip infusion cholangiog raphic-computed tomography demonstrated communication between an intrahepat ic cyst and the biliary system preoperatively. Drip infusion cholangiograph ic-computed tomography, a simple and noninvasive examination, is useful for differentiating biliary cystadenoma/cystadenocarcinoma from other intrahep atic cystic lesions.
