    INPUT: Portable semi-upright chest radiograph is obtained . Interval increase in right pleural effusion with near - complete opacification of the right hemithorax . The left lung is clear aside from mild haziness at the left lung base which could represent an area of aspiration . The heart appears enlarged , though this is stable . Mediastinal contour is widened , though this is likely due to technique . The imaged osseous structures are intact .
    OUTPUT:
    
Near - complete opacification of the right chest is likely a combination of consolidation and effusion . Vague opacity at the left lung base could also represent consolidation , possibly aspiration . Please refer to outside hospital CT for further details .
