Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low with bronchovascular crowding . A right pleural effusion is probably moderate in size . There is likely associated compressive atelectasis . No evidence of the left pleural effusion . Opacity in the right lower lobe of consolidation is again seen . Heart size can not be accurately assessed on this single AP view and low lung volumes , probably normal . No edema or pneumothorax . Asymmetric right apical pleural thickening with an apical opacity / mass is better appreciated on the prior CT .
    OUTPUT:
    
1 . Moderate right pleural effusion . 2 . Right lower lobe opacity similar to prior chest CT . 3 . Right apical pleural thickening and mass seen on prior chest CT . 4 . Low lung volumes .
