    INPUT: Lung volumes are low . Heart size appears mildly enlarged , unchanged . The aorta is tortuous . Hilar contours are unremarkable . Chain sutures from prior right upper lobe wedge resection are again noted . Streaky opacities in the lung bases likely reflect areas of atelectasis and scarring without focal consolidation . Pulmonary vasculature is not engorged . No pleural effusion or pneumothorax is present . No acute osseous abnormalities are visualized .
    OUTPUT:
    
Status post right upper lobe wedge resection . Low lung volumes with patchy opacities in the lung bases likely reflective of atelectasis and scarring .
