FINDINGS:
Heart size is normal.  Cardiomediastinal silhouette and hilar contours are
 unremarkable.  There is increased density at the right lung base which has
 posterior correlate on lateral view which could be representative of
 atelectasis, aspiration or pneumonia.  Lungs are otherwise clear.  There is no
 pleural effusion or pneumothorax.

IMPRESSION:
Increased density at the right lung base with posterior-lateral correlate
 which could represent atelectasis, aspiration or pneumonia.
