Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Right - sided PICC tip terminates in the proximal right atrium . Moderate enlargement of the cardiac silhouette is re - demonstrated . The mediastinal contour appears unchanged . Bilateral hilar enlargement with perihilar haziness and vascular indistinctness is compatible with mild pulmonary edema , slightly worse in the interval . A large right pleural effusion is substantially increased in the interval . A small left pleural effusion is also likely present . Bibasilar opacities likely reflect areas of atelectasis . No pneumothorax is identified .
    OUTPUT:
    
Mild pulmonary edema , worse in the interval . Substantial increase in size of large right pleural effusion with bibasilar airspace opacities , potentially atelectasis , but infection is not excluded . Small left pleural effusion is without substantial interval change .
