    INPUT: Heart size is moderately enlarged , increased when compared to the previous radiograph , but similar in size compared to the previous CT , and likely reflects a combination of cardiomegaly and a small to moderate pericardial effusion given the globular configuration . Pulmonary vasculature is normal . Mediastinal and hilar contours are stable . Small bilateral pleural effusions are noted with retrocardiac opacity , possibly reflective of atelectasis . No pneumothorax is demonstrated . No acute osseous abnormalities seen .
    OUTPUT:
    
1 . Moderate enlargement of the cardiac silhouette likely reflective of a combination of cardiomegaly and small to moderate pericardial effusion . 2 . Small bilateral pleural effusions with retrocardiac opacity , likely atelectasis . 3 . No evidence of pulmonary edema .
