RESUMEN
Hydatic pulmonary embolism is rare which can be complicated by chronic cor pulmonale and respiratory chronic failure. A 37-year-old woman, who had been operated twice for hydatic cystic, was hospitalized for cough, exercise-induced dyspnea and vomic, which had developed over the previous month. The standard chest Xray was normal. Imaging findings [angioscanner and cardiac echography] showed a hydatic pulmonary embolism which started from hydatic cysts on the right heart. Hydatic pulmonary embolism is due to the spread hydatic elements in the pulmonary circulation. It results from the rupture of hydatic cyst on the right heart. Clinical manifestations are dominated by cough, hemoptysis, vomic and exercise-induced dyspnea. Positive diagnosis has benefited from imaging especially angioscanner and cardiac echographic findings. Prognosis is particularly poor. The treatment is mainly surgical aiming at curing the primal cyst
