Huge mediastinal germ cell tumor with “white‐out” chest X‐ray imaging of the left lung

A 21‐year‐old man was brought to our hospital via ambulance because he could not move at all as a result of severe dyspnea. Chest X‐ray showed diffuse consolidation with “white‐out” of the whole left lung and a shift of the mediastinum toward the right (Fig (Fig1).1). Chest contrast enhanced computed tomography (CT) showed an irregularly enhanced huge mass in the left thorax and there was no air component in the left lung (Fig (Fig22)
