Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: AP upright portable view of the chest was obtained . The lungs remain hyperinflated with flattening of the diaphragms and areas of left base scarring suggesting chronic obstructive pulmonary disease / emphysema . The patient is rotated to the right . New since the prior study , there is right basilar opacity , raising concern for infection or aspiration . The cardiac silhouette remains mildly enlarged . The aorta is tortuous . There is slight blunting of the costophrenic angles which may relate to the hyperinflated lungs and basilar scarring without definite pleural effusion seen . There is no evidence of pneumothorax .
    OUTPUT:
    
1 . Right base opacity raises concern for consolidation , possibly due to infection or aspiration . 2 . Chronic changes of COPD / pulmonary emphysema .
