↓  Figure 1. Computed tomography angiography (CTA) pulmonary chest X-ray obtained on the day of admission demonstrates bilateral pleural effusions (circled) and a mediastinal mass causing severe superior vena cava (SVC) compression and right upper lobe pulmonary artery obstruction (arrow).
Figure 1.
↓  Figure 2. Computed tomography (CT) scan of the chest obtained on hospital day 2 shows a 13 × 16 mm mass in the lateral right upper lobe with irregular margins and extension to the pleura, consistent with findings during early hospitalization for suspected superior vena cava (SVC) syndrome.
