Echinococcal cysts located inside the pulmonary artery are extremely rare. The cause is usually rupture of intracardiac cysts or, more rarely, dissemination from a hepatic focus. The case of a 39-year-old patient with multiple hydatid cysts in the right and left pulmonary arteries and left ventricle wall is reported. The patient had undergone surgery for a hepatic hydatid cyst 10 years ago. Multidetector computed tomography angiography and magnetic resonance imaging were performed for the diagnostic evaluation.
