Anterior Mediastinal Mass Mimicking Supravalvular Pulmonary Stenosis With Systolic Murmur

Abstract

Pulmonary stenosis can occur as an isolated valvular lesion associated with congenital structural cardiac anomalies. Rarely, patients may develop an acquired form of pulmonary stenosis. We report a case of a rare presentation of anterior mediastinal teratoma mimicking congenital valvular heart disease, with complete resolution of her symptoms postoperatively.
