The cardiomediastinal and hilar contours are within normal limits.  As
 compared to prior examination, there has been interval development of diffuse
 bilateral parenchymal opacities.  No definite focal consolidation, pleural
 effusion or pneumothorax identified.

IMPRESSION:
New diffuse bilateral parenchymal opacities, findings raise concern for
 atypical pneumonia.  Interstitial pulmonary edema difficult to exclude.
