[Hydatid pulmonary embolism].

Hydatid pulmonary embolism is an uncommon condition resulting from the rupture of hydatid heart cyst or the opening of a visceral hydatid cyst often in the liver into the venous circulation. We report a case of 60 years old woman, admitted to hospital for acute heart pulmonale due to fistulization of an hepatic hydatid cyst into the inferior vena cava.
