    INPUT: The heart size remains moderate to severely enlarged . Mediastinal contour is unchanged . Mild pulmonary edema is re - demonstrated , perhaps minimally improved in the interval . Small bilateral pleural effusions are relatively unchanged . Bibasilar airspace opacities are also similar , and again may reflect compressive atelectasis . No pneumothorax is identified . The osseous structures are diffusely demineralized .
    OUTPUT:
    
Persistent mild pulmonary edema , minimally improved , with small bilateral pleural effusions . Similar appearing bibasilar airspace opacities , likely reflective of compressive atelectasis , but aspiration or pneumonia is not excluded .
