Incidental Asymptomatic Giant Hydatid Cyst of the Interventricular Septum Bulging Into the Right Ventricle

Abstract

Hydatid disease is caused by the larvae of Echinococcus granulosus. Domestic animals like cats and dogs are the primary carriers of echinococcal organisms. This parasitosis is still endemic in some particular regions of the world. The cardiac hydatid cyst is an exceptional infection. We report a case of an asymptomatic giant cardiac hydatid cyst in the interventricular septum (IVS) protruding in the right ventricular diagnosed incidentally by scan tomography during acute pancreatitis emergency. Transthoracic echocardiography revealed a cystic mass in the IVS bulging into the right ventricle. The diagnosis was confirmed by a cardiac CT scan.
