    INPUT: Persistent large right pleural effusion with adjacent atelectasis in the right middle and right lower lobe . Pulmonary vascular congestion is accompanied by diffuse interstitial edema , similar to the recent radiograph . There is no evidence of left pleural effusion . Nonspecific pleural and parenchymal scarring at right apex are again demonstrated .
    OUTPUT:
    
Large right pleural effusion with adjacent atelectasis . Diffuse interstitial opacities most likely due to interstitial edema , but followup radiographs would be helpful after diuresis to ensure resolution and to exclude other causes of diffuse lung disease .
