A rolling ball like mass in right atrium of a 6 year old child

Cardiac myxoma is a common tumor occurring more commonly in the left atrium in adult females. Its occurrence in pediatric age group is rare; the more common tumors are rhabdomyoma and fibroma. Presentation of myxoma on the right side is still rarer in this age group. We report a case of a 6-year-old male child who presented with prolonged fever. On examination, there is an extra diastolic sound with mid-diastolic murmur. Echocardiogram is suggestive of a large ball-like polypoidal mass rolling in the right atrium traversing into the right ventricle. The case was immediately operated, and histopathology confirmed the tumor as myxoma. High index of suspicion is required to diagnose the condition to prevent disastrous complications as the presentation is often enigmatic because of vague constitutional findings in most of the cases.
