Tropical Gastroenterology. 1998 Jul-Sep; 19(3): 115-7http://imsear.searo.who.int/handle/123456789/124698Intrabiliary rupture leading to biliary obstruction is a rare but serious presentation of hepatic echinococcosis. Four such cases are presented. Imaging studies including sonography, computed tomography and/or cholangiography, done in all patients led to a definite preoperative diagnosis which was later confirmed at surgery. Biliary tree dilatation was detected in three out of four patients, hydatid contents were seen in three patients and definite cysto-biliary communication was documented in two.engAdultBile Duct Diseases --diagnosisCholangiopancreatography, Endoscopic RetrogradeDiagnosis, DifferentialEchinococcosis, Hepatic --diagnosisFemaleHumansLiver Diseases --diagnosisMaleMiddle AgedRupture, Spontaneous --diagnosisTomography, X-Ray ComputedCase Reports
