Intrabiliary rupture of a large liver echinococcal cyst in an adolescent managed with endoscopic sphincterotomy and albendazole.

We report the case of a 17-year-old male with a rupture into the biliary tract. The patient was urgently admitted to the surgical department with the clinical diagnosis of cholangitis. Modern imaging techniques and specific serologic tests established the diagnosis of intrabiliary rupture of a liver hydatid cyst due to E. granulosus. Despite the fact that surgery remains the cornerstone of treatment, conservative management was preferred, due to the location of the echinococcal cyst in the right lobe of the liver adjacent to the inferior vena cava and the age of the patient. Endoscopic sphincterotomy was performed with subsequent evacuation of the biliary tree, followed by a sixcycle treatment with albendazole. At one-year follow-up, the patient is in good health, with no radiologic or serologic evidence of relapse.
