Abstract:
Objective To probe the characteristics of the ultrasonography of the intrahepatic duct cystic tumor(IDCT).Methods The ultrasonography of 12 patients with IDCT was analysed.The results were compared with the operation and pathology.Two of them were intraductal papillary adenomas,six were papillary adenocarcinomas,two were biliary cystadenomas and two were biliary cystadenocarcinomas.Results The ultrasonic diagnostic rate was 75%(9/12).The bile ducts of 10 cases(83%) were cystically dilated.Seven cases(58%) with thick walls of bile ducts were all malignant.Six tumors(50%) with intraluminal papillate echoes could be malignant or benign.The tremellose echoes were detected in 7 cases(58%) and the common bile ducts of six cases were obstructed by the tremellose substance.Conclusions It is the important diagnostic basis of IDCT that the bile ducts in some liver lobal or segment are dilated without reasons,with the thick bile duct wall and the poor ultrasound penetration,especially when the bile ducts are full of tremellose substance and the papillomas are detected in the ducts.It is of significance in the clinic to raise the early diagnostic rate of IDCT by ultrasound.
