An eight-year-old boy treated for a local recurrence of a stage IV parameningeal rhabdomyosarcoma complains four months after a second complete response, from dyspnea, chest pain and cyanosis. Imagery showed a bulky pleuro-mediastinal lesion. Echocardiography revealed a massive right atrial mass suggestive of metastasis. A partial response (70%) was obtained after four courses of chemotherapy, but progression was observed after ten cycles of chemotherapy and patient died one month later.This case of incidentally diagnosed heart metastases is particular because it occurred in a child and the primary tumor was a parameningeal rhabdomyosarcoma.
