Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single portable upright AP film . The patient is status post right upper lobectomy with redemonstration of volume loss in the right lung and rightward shift of mediastinal structures . Emphysematous changes are again seen . Pleural thickening along the right apicolateral chest is unchanged from the recent prior radiograph . New mild pulmonary edema is seen with vascular indistinctness . Small bilateral pleural effusions are noted , new on the left , and increased size on the right compared to the prior radiograph . Bibasilar opacities are seen , which likely reflect atelectasis , but can not exclude infection . Right hilar fullness is again noted , which reflects a prominent right pulmonary artery and adjacent lymphadenopathy . Cardiomediastinal silhouette is otherwise stable from prior exam . There is no pneumothorax . Several clips project over the upper thoracic spine and right lateral apex .
    OUTPUT:
    
Mild pulmonary edema and small bilateral pleural effusions . Bibasilar opacities likely reflect atelectasis , but infection is not excluded .
