The cause is usually rupture of an intracardiac cyst or dissemination from a hepatic focus either spontaneously or secondary to surgery. In this article, we report a 32-year- old patient with a history of hepatic and pulmonary hydatid cyst resection, presenting with multiple hydatid cysts located in the right pulmonary artery, and complaints of dyspnea and hemoptysis. Keywords: Computed tomography; hydatid cyst; magnetic resonance imaging; pulmonary artery cyst. Hydatidosis is a parasitic infection caused by ingesting food contaminated with the larvae of Echinococcus granulosis. After ingestion, parasite’s eggs hatch and the embryos penetrate through the intestinal mucosa and reach the liver via portal venous system. Liver and the lung filter 60% to 70% and 15% to 25% of the embryos, respectively; the remaining embryos may disseminate through systemic vessels and involve any organ system. [1,2] Pulmonary artery involvement by hydatid cysts is extremely rare and may be seen due to either rupture of an intracardiac cyst or dissemination from a hepatic focus spontaneously or secondary to surgery. Cysts within pulmonary arteries are associated with a high mortality rate due to the risk of embolization and anaphylactic shock. [3] In this article, we report a case of hydatid cysts located in right pulmonary arteries with a history of hepatic and pulmonary hydatid cysts.
