Hydatid cyst of the interventricular septum and contribution of magnetic resonance imaging.

Cardiac echinococcosis has not been reported frequently. Because of the risk of potentially lethal complications, early diagnosis and definitive treatment are very important. We report a case of a cardiac echinococcal cyst in the interventricular septum. The cyst that caused angina and showed ischemic changes in electrocardiogram was diagnosed by two-dimensional echocardiography and magnetic resonance imaging and was treated surgically.
