Linear areas of atelectasis are present in the left mid lung and left lung
 base, as well as postsurgical changes related to prior right upper lobe
 resection. Otherwise, the lungs are relatively well inflated, with no focal
 consolidation, large pleural effusion, or pneumothorax. The cardiomediastinal
 silhouette is stable.
