FINDINGS:
Frontal and lateral chest radiographs demonstrate slight increase
 in size of left lower lung airspace opacity with increased retrocardiac
 component.  The lungs are otherwise clear, the cardiac silhouette is normal. 
 The mediastinal contours are unremarkable.  Pulmonary vasculature is normal.

IMPRESSION:
Slight interval increase in left lower lung opacity compatible
 with slightly worsening pneumonia.
