Progression of previously noted air space disease in the right middle and lower lobes, with obliteration of air bronchograms. The left lung is clear of pleural effusions, but there is blunting of the lateral costophrenic angle, possibly due to scarring. A left retrocardiac opacity is noted, which may represent vessels or subsegmental linear atelectasis.
