Neverthless, hydatid pulmonary embolism is an uncommon condition. We report a case of primary cardiac hydatid cyst in which hydatid materials caused recurrent embolizations in pulmonary arteries and pulmonary parenchyma.Case presentation: A nineteen-year-old girl, was admitted to Charles Nicolle hospital reporting eight months history of anorexia, asthenia and cough.The physical examination results were normal. Chest radiography revealed a convex middle arch and multiple bilateral homogenous circular opacities. Electrocardiographic finding was a right ventricular hypertrophy. Echocardiography showed a cystic mass developed from the lower and the side right ventricular wall, which restrain tricuspid orifice with a 38 mmhg mean PAP. A CT chest-abdominal scan examination revealed the presence of an hypodense cystic lesion of 4 cm in the right ventricle with right pulmonary artery embolism, and multiple bilateral parenchymatous excavated nodule associated to a calcificated cystic lesion in VII segment of the liver. Serologic test results for echinococcus by means of an enzyme-linked immunosorbent assay and an indirect haemagglutination test were positive. Cysts were punctured, aspirated, and resected. Upon discharge from the hospital, patient was prescribed 10mg/kg/day of albendazole.Conclusion: Hydatid pulmonary embolism is one of the inescapable complication of left heart Echinococcosis. It is rare but serious. There is no consensus of treatment. Early diagnosis is essential because delayed treatment increases the morbidity and mortality rates. %U
