    INPUT: Frontal and lateral chest radiographs demonstrate interval decrease in size of cardiac silhouette ; however , there is similar " water bottle " configuration to the cardiac silhouette suggesting persistent pericardial effusion . Right pleural effusion is decreased , now small to moderate in size . Faint opacification projecting over the right lower lung likely reflects residual atelectasis . No pulmonary nodules identified .
    OUTPUT:
    
Decreased cardiac silhouette with configuration suggesting residual small pericardial effusion . Slight interval decrease in size of right pleural effusion .
