Cardiopulmonary Echinococcus Infection.

Cystic echinococcosis (CE), a zoonotic infection caused by Echinococcus granulosus, primarily affects the liver and lungs. However, cardiac involvement is uncommon. This case report presents an unusual instance of heart involvement in a patient with CE. A 28-year-old man from India presented with a persistent cough and hemoptysis. Imaging revealed bilateral lung lesions along with cystic lesions in his right ventricle. The echinococcal serology result was positive, and a surgical biopsy from the lung demonstrated necrotizing granulomatous inflammation with laminated eosinophilic material, consistent with echinococcosis. This case highlights the possibility of cardiac involvement in CE and the challenges associated with its diagnosis and management.
