Large cardiac rhabdomyoma in two infants: Good response to medical management – A brief report

Abstract

Rhabdomyomas are rare tumors in children often associated with tuberous sclerosis. They are usually diagnosed during antenatal period or as an incidental finding. The first case is a 2.5-month-old child who was diagnosed to have rhabdomyomas at gestational age of 24 weeks. Electrocardiogram revealed left axis deviation and multiple premature atrial contractions. Echocardiography showed massive tumor occupying the right ventricular cavity. Tuberous sclerosis was seen on magnetic resonance imaging. He was commenced on everolimus with obvious regression of tumor. The second case is an 8-month-old male who was referred to us for cardiac evaluation. Echocardiography showed two masses of rhabdomyoma. He was also placed on everolimus but was lost to follow-up. Rhabdomyomas are rare tumors of the heart which respond well to chemotherapy.
