Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Single AP upright portable view of the chest was obtained . There are low lung volumes , which accentuate the bronchovascular markings . Given this , there is patchy right basilar opacity which could be due to atelectasis in combination with vascular engorgement , although consolidation from infection is not excluded . No large pleural effusions are seen , although trace effusions will be difficult to exclude . There is no evidence of pneumothorax . Cardiac and mediastinal silhouettes are unremarkable . Hilar contours are prominent , likely accentuated by low lung volumes ; however , pulmonary vascular engorgement may be present .
    OUTPUT:
    
1 . Low lung volumes which accentuate the bronchovascular markings . Patchy right basilar opacity , pneumonia not excluded versus atelectasis . 2 . Prominence of the hila , likely accentuated by low lung volumes ; however , vascular engorgement may be present .
