Cardiac Tumor Presenting as Acute Right Hemiparesis in a 13-Year-Old Boy.

Among pediatric population, the most common primary cardiac tumor is rhabdomyomas, the second is fibroma, and myxoma is the third most common. 1 The clinical manifestation of cardiac myxoma depends on the tumor size, shape and surface contents. 2 The variable clinical symptoms can range from non-specific symptoms to some neurological deficits, or even cerebral stroke and peripheral embolisms due to thrombi from tumor fragments. 1-4 In literature review, most cardiac myxoma is located in left atrium and the size can range from small to as large as 8 cm. 3-5 Therefore, early diagnosis and management is important to save patient form morbidity, mortality and further complication. 2-4 We reported a 13-year-old boy with sudden onset of right hemiparesis. Further echocardiography revealed a huge mass in the left atrium. Cardiac myxoma was diagnosed after surgical removal of the mass.
