@entity4617 in @entity1 are rare, are more commonly benign, and differ in types when compared with those in adults. @entity4618 , @entity44 , and @entity81 are the most common @entity4617 in fetuses and neonates. In @entity1 and @entity1 , the most common @entity4617 are @entity4618 and @entity81 , which are benign primary @entity4617 , whereas in adults, @entity715 is the most common cardiac mass and @entity3291 is the most common primary @entity4617 . @entity242 are the most common primary @entity4617 in both @entity1 and adults. Metastatic @entity4617 are less common in @entity1 than in adults and include @entity242 , @entity706 , @entity5 , and @entity3969 . @entity1 with @entity4617 can be asymptomatic or may present with murmur, @entity943 , @entity712 , or @entity944 . Echocardiography is the primary modality for initial evaluation of symptomatic @entity1 . Cardiac magnetic resonance imaging provides further characterization of cardiac masses and @entity5 for diagnostic purposes and can be used to assess cardiac and extracardiac involvement for treatment planning. Treatment varies from conservative management or surgical resection to transplantation, depending on the diagnosis and the @entity1 's symptoms. @entity4618 typically regresses spontaneously during early childhood and does not require surgical intervention if asymptomatic. However, @entity81 is generally resected because it does not regress. An understanding of the types of @entity4617 that occur in @entity1 and @entity1 , their clinical implications and associations, and their imaging appearances will facilitate @entity1 management.
