Right atrial cardiac myxoma and multiple pulmonary artery aneurysms: Is there a causal relationship?

Cardiac myxomas are rare occurrences in pediatric populations, as are pulmonary artery aneurysms. We report a 17-year-old adolescent with right atrial cardiac myxoma and concomitant multiple peripheral pulmonary artery aneurysms. Histological examination indicated infiltration of the pulmonary artery wall through the embolic cardiac myxoma cells, thereby weakening it. This report highlights the probable causal relationship between these two entities, proposes the possible pathomechanism and presents the diagnostic and therapeutic dilemmas in the management of this condition.
