[Intrabiliary rupture of hepatic hydatid cyst]

Spontaneous hepatic hydatid cyst rupture into the biliary tract is unusual. The authors describe a case of a 62-year-old man with a hepatic hydatid cyst, showing that it is possible to confirm rupture into the biliary system with cholangiography-MRI. Surgical treatment remains the best form of management. Endoscopic management is a therapeutic possibility in all cases in which surgery is contraindicated. In the case observed endoscopic sphinctererotomy resolved the biliary obstruction, while the hydatid cyst was treated by transbiliary irrigation with scolicidal solutions and pharmacological therapy. The treatment permitted complete clinical resolution of the hepatic hydatosis.
