Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Low lung volumes are noted . There is a moderate - large left and small right pleural effusion , some increase on the prior examination . The left hemidiaphragm and left heart border are obscured , likely secondary to pleural effusion and adjacent atelectasis , although underlying consolidation can not be excluded . Additionally , there is bilateral hilar prominence and cephalization of the pulmonary vasculature , suggestive of pulmonary edema . There is no pneumothorax identified . The cardiomediastinal silhouette is partially obscured but appears enlarged , unchanged as compared to the prior examination . Moderate - severe , right acromioclavicular joint degenerative changes are noted .
    OUTPUT:
    
1 . Moderate - severe left and small right pleural effusions , cardiomegaly , and pulmonary edema suggestive of volume overload . 2 . The combination of atelectasis and pleural effusions obscure the left heart border and left hemidiaphragm , and underlying consolidation is likely .
