    INPUT: Bronchovascular markings remain prominent . There is streaky density at the lung bases most consistent with subsegmental atelectasis . There is somewhat asymmetric density at the right lung base . The cardiac silhouette is prominent but may be exaggerated by portable technique . The aorta is calcified . Mediastinal structures are stable . The bony thorax is grossly intact .
    OUTPUT:
    
Stable examination except for asymmetric density at the right lung base that may be due to some volume loss . Focal consolidation can not be excluded . A lateral view may be helpful if further evaluation is clinically indicated .
