Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP upright and lateral views of the chest were provided . There has been interval increase in left basal opacity which likely reflects a combination of a moderate - sized joint effusion with basilar consolidation which could represent atelectasis versus pneumonia . At the right lung base , there is mild atelectasis and a moderate pleural effusion which is increased from prior exam . Pulmonary interstitial edema persists . The heart size can not be assessed . Mediastinal contour appears grossly stable . No pneumothorax is seen . Bony structures are intact . No definite signs of free air below the right hemidiaphragm . Clips are seen in the upper abdominal midline .
    OUTPUT:
    
Interval increase in bilateral pleural effusions , left greater than right , with bibasilar opacities , left greater than right , likely atelectasis though can not exclude infection . Mild pulmonary interstitial edema persists .
