Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Overall lung volumes are lower than the prior examination . There are increasing bibasilar opacities . Pleural effusions likely exist bilaterally with at least a definite moderate effusion on the right . Opacities may reflect progressive consolidation secondary to pneumonia , aspiration , or atelectasis . Prominence of bronchovascular markings may be partly due to lower lung volumes , though superimposed edema is also likely . Assessment of cardiac contours is difficult secondary to bibasilar opacities . No pneumothorax is evident .
    OUTPUT:
    
Increasing bibasilar opacities , likely a combination of bilateral effusions and pneumonia . Opacities could also reflect aspiration or atelectasis . Mild superimposed pulmonary edema is also likely .
