Abstract:
Objective To evaluate the value of MSCT in the diagnosis of extrahepatic cholangiocarcinoma.Methods The MSCT appearances of extrahepatic cholangiocarcinoma confirmed by pathology in 27 cases were analyzed retrospectively.Among them,20 patients underwent plain and four-phase dynamic contrast-enhanced CT scans including early arterial phase,late arterial phase,portal phase and delay phase,7 patients only underwent contrast-enhanced CT scans.Results 15 lesions were located in the hilar and 12 lesions were located in the common bile duct.CT features of cholangiocarcinomas in this group were varied with its position and growth pattern.Besides the direct sign such as delay enhancement,the indirect findings were also specific such as hepatic lobe atrophy,dilated bile duct,etc.Conclusion MSCT is of great value in diagnosis of extrahepatic cholangiocarcinoma.
