Abstract
The objective of this study was to describe the myxoma of the right atrium occurring in an 11-year-old girl. It was an 11-year-old girl weighing 22 kg, admitted for exertional dyspnea, dry cough, palpitations, hepatitis, abdominal bloating, fever evolving for more than 9 months without a history of known cardiovascular disease; referral from a pulmonology department for cardiomegaly and right pleurisy. At cardiac auscultation, the rhythm was irregularly fast at 130 beats without added noise with a blood pressure of 110/65 mmhg. In the lungs, there was silence and a decrease in vocal vibrations at the right base, SaO2 at 70%. Elsewhere a thoracic collateral venous circulation was visible. Electrocardiogram recorded rapid atrial fibrillation at 134 cycles. The cardiac ultrasound concluded that there was a mobile mass in the right atrium prolapsing in the right ventricle measuring 25 mm × 18.9 mm suggesting a myxoma. The myxoma of the right atrium is of a rare localization with a polymorphic clinical manifestation. It should be diagnosed as early as possible to avoid the occurrence of dreaded complications. Its management is surgical.

Summary
About 80% of primary cardiac tumors are benign, more than half of which are myxomas [1]. The atrium myxoma is a rare benign tumor. Its location in the right atrium is unusual and is found in 15% to 20% of cases of cardiac myxoma. This form can be complicated by pulmonary embolism and right heart failure and it is characterized by a clinical picture often misleading [3] [4] [5].
