Abstract:
Objective To analyze the CT features of hepatic echinococcosis rupture into the biliary tract, and to assess the value of CT study in the diagnosis of such cases. Methods CT findings in 15 cases proved surgically and pathologically were studied and analyzed retrospectively. Results 15 patients had 20 hepatic echinococcosis, including simple echinococcosis with single cyst (9 lesions), simple hydatid cyst with multiple cysts (6 lesions), and multivesicular echinococcosis with multiple cysts (5 lesions). 2 lesions had calcifications on the cyst wall. The rupture of hepatic echinococcosis into the intrahepatic ducts was found in all 15 cases. Meanwhile, 12 of them had rupture into the common bile duct, and 2 into the gallbladder. The main CT findings were hepatic echinococcosis incorporated with the dilatation of the biliary tract. Conclusion Signs of rupture of hepatic echinococcosis into the biliary tract are characteristic in CT studies, providing a reliable evidence for preoperative diagnosis.
