[Hemangioma of the right ventricular outflow tract, clinical report].

Cardiac hemangiomas are a rare benign primary tumor with an estimated incidence of no more than 10% of cases of primary cardiac tumors. They can arise in any location but most of them occur predominantly in the right ventricle. Heart hemangiomas are usually asymptomatic and accidentally diagnosed by imaging methods such as echocardiography or nuclear magnetic resonance; however they can cause symptoms resulting from obstruction of blood flow, interference with the heart valves, arrhythmias or embolization. Surgical resection is the treatment of choice and long-term prognosis is favorable after total resection of the tumor. The authors present a case of cardiac hemangioma whose clinical diagnosis was triggered by exertional dyspnea and culminating with complete resection of the tumor. In this context, a review of this entity is made with special emphasis on imaging modalities used for diagnosis.
