Abstract
Intrapericardial tumors,
especially rhabdomyomas, are rare. Most intrapericardial tumors in fetuses and
children have anechoic cystic areas, characteristic of teratomas. Rhabdomyomas
are solid masses, usually with a finely speckled echocardiographic appearance.
Even though rhabdomyomas are the most common prenatally detected primary
cardiac tumors, they infrequently present as intrapericardial masses.
Pillgram-Larsen et al described an intramural rhabdomyoma originating from the
right atrium with intrapericardial extension in a young adult. We describe an
unusual prenatally detected solid intrapericardial mass, confirmed postnatally
to be a rhabdomyoma.
