Introduction: right atrial myxoma is a rare disease among children and its clinical presentation is not specific. case presentation: we reported a four-year-old girl with exertional dyspnea in whom investigations revealed a huge right atrial myxoma. the evolution was quite unusual; the girl presented syncope secondary to an intermittent prolapse of the tumor through the tricuspid valve. after complete resection, her symptoms were relieved without any recurrence of the tumor. conclusions: the authors emphasize on the rarity of this pathology among children, its clinical polymorphism, the necessity of a rapid diagnosis, and an appropriate treatment to avoid complications and recurrence of the tumor.
