Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lung volumes are low . Cardiac silhouette size appears mildly enlarged . Mediastinal and hilar contours are unchanged . Pulmonary vasculature is not engorged . Streaky and patchy opacities in the lung bases are again noted , possibly reflective of atelectasis . Minimal blunting of the costophrenic angles on the lateral view posteriorly suggests trace bilateral pleural effusions . No pneumothorax is identified . No acute osseous abnormality is seen .
    OUTPUT:
    
Low lung volumes with patchy opacities in the lung bases likely atelectasis and probable trace bilateral pleural effusions . Please note that infection or aspiration can not be completely excluded in the correct clinical setting .
