A Teenage Girl with Large Lung Mass

Abstract

Extraskeletal Ewing Sarcoma is rarely reported. A fifteen-year-old girl presented with the right-sided pleuritic chest pain, shortness of breath, and productive cough with whitish sputum associated with poor oral intake. She subsequently underwent contrast-enhanced Computerized Tomography thorax, which showed lobulated heterogenous hypodensity occupying the entrance of the right superior pulmonary vein, extending to the left atrium.
