Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are slightly improved when compared to the prior study with increased aeration of the right lung base . A previously seen right pleural effusion appears to have decreased however there is new airspace opacity seen in the right middle and right lower lobe . This may reflect re-expansion pulmonary edema however infection can not be excluded . Prominence of the pulmonary vasculature consistent with background congestive heart failure . Left basilar atelectasis . Deformity of the right shoulder consistent with an old fracture .
    OUTPUT:
    
Improved aeration overall in the right lung base with improvement in the right pleural effusion . However , there is new consolidation in this area which likely may reflect re-expansion pulmonary edema or infection . The right hilum appears prominent but this can not be separated from the area of consolidation .
