Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Frontal and lateral views of the chest were obtained . The lungs are hyperinflated with flattening of the diaphragms and increased AP diameter , consistent with chronic obstructive pulmonary disease . There is a small right pleural effusion . Additionally , patchy bibasilar opacities are seen , which could be due to pneumonia . An additional a small patchy opacity is seen in the left mid lung zone which may also be post-infection ; however , recommend followup chest radiograph or CT after antibiotic treatment to assess for resolution and exclude underlying pulmonary nodule , particularly in this patient with COPD . No evidence of pneumothorax is seen . The cardiac silhouette is not enlarged . The aorta is calcified and tortuous .
    OUTPUT:
    
1 . Bibasilar opacities and additional patchy left mid lung opacity raise concern for multifocal pneumonia . Possible additional right mid lung opacity . Recommend followup chest radiograph or CT after appropriate antibiotic treatment to exclude underlying pulmonary nodule ( s ) , particularly in this patient with COPD . 2 . Small right pleural effusion .
