case_images: Identical fluoroscopic images of the chest taken after the placement of a pigtail catheter and chest tube. (a) Unlabelled image. (b) On fluoroscopic images, the darker radiopaque area in the apical field peripheral to the partially collapsed lung in the left upper lobe (grey shaded area with black lines), indicates the absence of air, suggesting atelectasis rather than pneumothorax. Red arrows indicate the pigtail catheter and chest tube.

case_images: As the angiographic imaging system (Artis Zee, Siemens Healthcare, Germany) was readily available in the cardiac catheterization suite, fluoroscopic images of the chest (Fig. 1) were quickly obtained to investigate the possibility of endobronchial intubation and pneumothorax. Due to this unexpected finding, the fluoroscopic images were reviewed again by the same attending anaesthetist and interventional cardiologist, along with the cardiac surgeon, who then diagnosed atelectasis rather than pneumothorax (Fig. 1).
