    INPUT: Airspace opacification of bilateral lung bases , particularly on the right , has increased compared with the prior study and may represent worsening pulmonary edema or developing consolidation . Pulmonary vascular congestion has also increased and there small pleural effusions , likely new . There is no pneumothorax . The cardiomediastinal silhouette is stable .
    OUTPUT:
    
Increased airspace opacities , worsening pulmonary vascular congestion , and new small bilateral pleural effusions suggest worsening pulmonary edema . A superimposed consolidation , particular within the right lung base , can not be entirely excluded .
