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.
