Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Lungs are hyperinflated , consistent with COPD . There are sternotomy wires . Mild prominence of the cardiomediastinal silhouette is present . Possible mild prominence the pulmonary arteries , which could reflect pulmonary hypertension . There is a small left effusion , with underlying collapse and / or pneumonic consolidation . There is prominent platelike atelectasis at the right lung base . Platelike atelectasis is noted in the right lung base . In addition , in the right suprahilar midlung there is a relatively faint , elongated , somewhat irregular density . This may represent architectural distortion from underlying parenchymal disease , however this lesion is incompletely characterized . The patient 's head overlies the medial portion of both lung apices . Allowing for this , no obvious pneumothorax is identified . There is upper zone redistribution , without overt CHF .
    OUTPUT:
    
1 . Consolidation at the left lung base may represent compressive atelectasis from an adjacent small pleural effusion , however underlying pneumonia can not be excluded . 2 . An opacity in the right midlung is incompletely characterized and nonemergent chest CT is recommended for further evaluation . 3 . COPD , cardiomegaly with sternotomy wires , upper zone redistribution , without overt CHF .
