[Cardiac echinococcosis].

Cardiac hydatid disease is rare. We report on an uncommon hydatid cyst localized in the right ventricular wall, right atrial wall tricuspid valve, left atrium and pericard. A 33-year-old woman was treated for cough, fever and chest pain. Cardiac echocardiographic examination revealed a round tumour (5.8 x 4 cm) in the right ventricular free wall and two smaller cysts behind that tumour. There were cysts in right atrial wall and tricuspidal valve as well. Serologic tests for hydatidosis were positive. Computed tomography finding was consistent with diagnosis of hydatid cyst in lungs and right hylar part. Surgical treatment was rejected due to great risk of cardiac perforation. Medical treatment with albendazole was unsuccessful and the patient died due to systemic hydatid involvement of the lungs, liver and central nervous system.
