Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The patient is status post sternotomy . The cardiac , mediastinal and hilar contours appear stable . The lung volumes are low . There is no pleural effusion or pneumothorax . Widespread hazy and interstitial opacities are most suggestive of pulmonary edema including indistinct upper zone re-distribution of pulmonary vasculature . Each hilum appears prominent , particularly the right , including a somewhat rounded appearance . This is probably due to edema , but short - term followup radiographs are recommended in order to exclude a persistent new right hilar contour abnormality .
    OUTPUT:
    
Findings consistent with pulmonary edema . Short - term follow - up radiographs are recommended in order to exclude new contour abnormality in the right hilum , however .
