[Asymptomatic @entity4617 in a XXXX : an incidental diagnosis].

@entity1 @entity5 @entity1109 @entity4617 @entity4618 @entity1729 @entity81
@entity4617 in the pediatric population are rare, their incidence range between 0.001% and 0.003%. They are mostly benign, @entity4618 the most common type, followed by @entity81 . The clinical features are being usually nonspecific and depend on the size and location of the @entity5 within the heart. We report the case of a previously healthy four-year-old @entity1 referred for @entity1109 . A @entity1729 was suspected and a chest X-ray showed an increased cardiothoracic index. An echocardiogram revealed a single large heterogeneous mass in the left ventricle emerging from the lateral wall. Despite its size, the mass did not obstruct the left ventricular outflow tract or affect mitral valve function. Cardiac magnetic resonance imaging showed a large mass whose imaging features were suggestive of a @entity81 . He became symptomatic during follow-up and was referred for surgical excision of the mass. Histological study confirmed a @entity81 . At present the @entity1 remains asymptomatic.
