FINDINGS:
The lungs are slightly low in volume with subtle bilateral lower lobe hazy
 opacities compatible with bibasilar atelectasis or early pneumonia.  There is
 no pneumothorax, pulmonary edema, or pleural effusion.  The cardiomediastinal
 silhouette is unremarkable.

IMPRESSION:
Hazy bibasilar opacities could reflect bibasilar atelectasis or early
 pneumonia in the appropriate clinical setting. Clinical correlation is advised
 and followup imaging should be based on the clinical assessment.
