    INPUT: Single AP upright portable view of the chest was obtained . Lingular mass was better assessed on recent prior CT . There is an interval development of mild pulmonary edema . Interval development of increased right medial lung base opacity most likely relates to fluid overload with possible underlying atelectasis rather than infection given it s short - term development . There is also increased opacity at the lateral left lung base , again may be due to atelectasis and / or related to fluid overload given short - term development . The cardiac and mediastinal silhouettes are stable . No large pleural effusion seen . The mediastinum is stable .
    OUTPUT:
    
Interval development of mild pulmonary edema . Increased bibasilar opacities , as above , most likely related to fluid overload with possible atelectasis rather than infection given the short - term development .
