Hepatic hydatid cysts with biliary, and peritoneal rupture and transdiaphragmatic migration.

Hydatid disease is a parasitic infection that most commonly involves the liver. Imaging plays a vital role in the diagnosis of this disease. Rupture of the cyst can give rise to a wide spectrum of complications. We describe a case of hepatic hydatid cyst with rupture into the biliary tree, right pleural cavity and dissemination into the peritoneal cavity, with associated splenic hydatid cysts. MRI may be a useful non-invasive diagnostic tool in such disseminated cases to define the complete extent of the disease.
