    INPUT: Patchy airspace opacities predominantly in a perihilar distribution and engorged pulmonary vasculature likely represent mild pulmonary edema . There is mild peribronchial cuffing . The cardiac and mediastinal contours are stable . There is no free air beneath the hemidiaphragms . There is no pleural effusion or pneumothorax .
    OUTPUT:
    
Patchy bilateral perihilar airspace opacities and peribronchial cuffing most likely indicates pulmonary edema ; atypical infection seems less likely although not excluded .
