FINDINGS:
Single frontal view of this semi-upright patient demonstrates low
 lung volumes accentuating bronchovascular crowding.  There appears to be
 increased mild perihilar vascular congestion without frank edema.  A rounded
 density in the right cardiophrenic angle may corresponding to a pulmonary mass
 in the right lung base is seen on same-day reference CT.  The heart is normal
 in size.  The thoracic aorta is mildly unfolded.  There is no pneumothorax or
 pleural effusion.

IMPRESSION:
1.  Mild pulmonary vascular congestion.
 2.  Right lower lobe lung mass is better demonstrated on accompanying
 reference CT.
 3.  Low lung volumes.
