Repeated discomfort leading to a diagnosis of a voluminous right atrial myxoma in an adolescent patient: a case report

Myxoma of the right atrium is rare, especially at young age. We report a voluminous right atrial myxoma in an adolescent admitted to the general pediatric ward for recurrent discomfort with deterioration of general condition, dyspnea and systemic inflammation. Transthoracic echocardiography revealed an intra-cardiac tumor 7.3 × 5.8 cm in diameter. After surgical excision, the post-operative outcome was favorable. Early diagnosis of cardiac myxoma is important to prevent the occurrence of complication. It should not be missed in a pediatric patient with repeated discomfort and systemic inflammation. Surgical excision remains the main treatment with favorable outcome.
