FINDINGS:
PA and lateral chest radiograph demonstrates obscuration of the right heart
 border with a confluent opacity.  This appears to be located within the right
 middle lobe as appreciated on the lateral chest radiograph, concerning for
 pneumonia. Lungs are hyper expanded with flattening of the diaphragms
 bilaterally consistent with emphysematous changes. Heart size is within normal
 limits. Mediastinal and hilar contours are within normal limits. There is no
 pleural effusion or pneumothorax. Chronic right humeral head deformity is
 noted.

IMPRESSION:
COPD with superimposed right middle lobe pneumonia.
