There has been interval removal of a right - sided chest tube , without evidence of pneumothorax . The right lung is clear . In the left lung , there has been interval development of perihilar and lower lung opacities , with obscuration of portions of the right hemidiaphragm margin . An oblong silhouette projecting over the left upper lung is likely external to the patient .
