    INPUT: The previously seen layering right pleural effusion has increased , now large and causing adjacent compressive atelectasis and mild leftward midline shift . There may be a small left pleural effusion , incompletely evaluated on this single AP radiograph . The mediastinal contour is difficult to evaluate due to effusion , but is likely stable . Pulmonary vascular congestion and mild pulmonary edema are present . There is no focal consolidation or pneumothorax .
    OUTPUT:
    
1 . Pulmonary vascular congestion and mild pulmonary edema . 2 . Interval increase in large right pleural effusion with adjacent compressive atelectasis and mild leftward shift of midline structures .
