    INPUT: Cardiac silhouette size appears at least moderate to severely enlarged , as seen on the CT chest , due to the presence of loculated pericardial fluid . Mediastinal and hilar contours are unchanged . Pulmonary vasculature is not engorged . Moderate size bilateral pleural effusions , larger on the right are increased compared to the previous chest radiograph . Bibasilar airspace opacities appear to reflect compressive atelectasis . No acute osseous abnormality is visualized .
    OUTPUT:
    
Moderate to severe enlargement of the cardiac silhouette , incompletely assessed , partly attributable to the presence of loculated pericardial fluid , as seen on the previous chest CT . Moderate size bilateral pleural effusions , larger on right , with bibasilar compressive atelectasis .
