    INPUT: There has been progression of the right - sided airspace opacity , this is bilateral but asymmetric . Given a predominately perihilar distribution , this is likely due to pulmonary edema . The heart is not grossly enlarged , within the limits of the projection technique . There is likely a small right - sided pleural effusion . No pneumothorax seen . A right - sided internal jugular catheter terminates in the mid SVC . A nasogastric tube is in - situ , the tip is not visualized lies below the left hemidiaphragm .
    OUTPUT:
    
Increased bilateral airspace opacities , greater on the right than the left likely reflecting asymmetric pulmonary edema . Infection can not be excluded .
