IMPRESSION:
The lung volumes are lower today than on  exaggerating the severity of
 very mild pulmonary edema. A roughly triangular region of consolidation in the
 right midlung has grown substantially since . Although fissural
 pleural effusion can have a similar appearance, I would first consider
 pneumonia. If greater certainty is necessary, CT scanning would be required.
 
 Borderline cardiomegaly is stable, and there are very small pleural effusions.
