    INPUT: Single AP portable view of the chest was obtained . There has been interval increase in small bilateral pleural effusions with overlying atelectasis . The cardiac silhouette is enlarged and appears somewhat globular in appearance , which could be due to an underlying pericardial effusion versus cardiomyopathy . Slight prominence and indistinctness of the hila may be due to pulmonary vascular engorgement . No pneumothorax is seen . The aortic knob is calcified .
    OUTPUT:
    
Small bilateral pleural effusions with overlying atelectasis . Basilar consolidation is difficult to exclude on this study . Enlargement of the cardiac silhouette with globular configuration , underlying pericardial effusion is not excluded .
