Hemangioma of the right ventricle causing outflow tract obstruction.
A 3 1/2-year-old child had a murmur of pulmonary stenosis. Echocardiography and cardiac catheterization revealed a pulmonary infundibular obstruction. Magnetic resonance imaging of the heart demonstrated a mass in the interventricular septum. The mass was successfully resected and a pathologic diagnosis of capillary hemangioma was made. Only two previous cases of hemangioma causing right ventricular outflow obstruction have been reported; both of these cases involved adults. This case represents the first report of a hemangioma causing right ventricular outflow tract obstruction in a child. An exploratory operation with resection is the treatment of choice.
