A rare case of biatrial myxoma in an 11-year-old girl patient with thromboembolic stroke: A case report.

INTRODUCTION

Cardiac myxomas (CM) are benign primary tumors typically found in the left atrium, but biatrial myxomas are exceptionally rare, comprising only 3-5 % of cases. This report highlights the rarity of biatrial myxomas in a young patient, the importance of early recognition due to the risk of thromboembolic events, which can lead to stroke. Excellent surgical intervention is needed to prevent CM recurrences.

CASE PRESENTATION: An 11-year-old girl presented with sudden onset of left-sided hemiparesis, aphasia, right-sided facial drooping, cephalgia, palpitations, nausea, and intermittent chest pain over the past two months. Laboratory examination revealed anemia and elevated D-Dimer. Echocardiography and cardiac CT demonstrated large masses in the right and left atrium, suggesting myxomas. The patient was diagnosed with biatrial myxomas complicated by thromboembolic stroke.

CLINICAL DISCUSSION: Complete mass evacuation was performed through median sternotomy. Histopathology examination confirmed CM.

CONCLUSION

This case emphasizes the importance of early detection, detailed examination and surgical intervention of biatrial myxomas, especially in young patients, to prevent and manage life-threatening thromboembolic complications and recurrence of CM. Timely intervention is crucial for ensuring favorable outcomes.
