The purpose of this study was to establish the role of MR cholangiopancreatography (MRCP) in the diagnosis of biliary rupture in hepatic hydatid disease. We sought to determine whether the morphologic features of cysts and bile duct abnormalities detected on MRCP are specific enough for identification of intrabiliary rupture.If one of the following MRCP findings of apparent connection between hydatid cyst and biliary system, deformation of cyst, focal defect in cyst wall, or beaklike projection extending from cyst wall was present in a patient with hepatic hydatid cyst, the sensitivity of MRCP was 91.7% and the specificity was 82.8% for identification of intrabiliary rupture.
