Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: The cardiac , mediastinal and hilar contours appear unchanged including moderate tortuosity of the aorta . There is moderate - to - severe relative elevation of the right hemidiaphragm as before . Streaky opacification associated with the elevated right hemidiaphragm would be compatible with chronic atelectasis . In addition , however , there is medial left basilar streaky opacity in the retrocardiac region , for which atelectasis could be considered versus pneumonia in the appropriate setting . Lastly , there is a focal new left mid lung opaciy , potentially a focus of bronchopneumonia . Background mild interstitial abnormality is unchanged and may be associated with slight congestion , although atypical infection could be considered in the appropriate setting .
    OUTPUT:
    
New left mid and lower lobe opacities , concerning for bronchopneumonia in the appropriate setting . Similar marked elevation of the right hemidiaphragm ; streaky opacification in the right lower lobe is compatible with associated atelectasis although infection is hard to exclude particularly since there is no direct prior comparison for the lateral view .
