A Case of Pulmonary Hypertension due to Chronic Pulmonary Hydatid Cyst Embolism

Hydatid pulmonary embolism is an uncommon condition resulting from the rupture of a hydatid cyst. We report a case of pulmonary hypertension due to chronic pulmonary hydatid cyst embolism. Our patient was 33 year old female. She was admitted to our hospital with complaints of progressive dyspnea and fatigue. Her past medical his­tory revealed surgical excision of hepatic hydatid cyst one year ago and pulmonary artery hydatid cyst embolectomy six month ago. On admission her pulmonary artery systolic pressure was 60 mmHg. Her CT angiography revealed bilateral lower lobe pulmonary arterial throm­bus. After the oral anticoagulation and albendazole treatment, repeated echocardiographic evaluations showed PAP as 50, 45, 30 mmHg.
