    INPUT: There is probable hyperinflation with background COPD . There are diffusely increased interstitial markings , with more pronounced bibasilar opacities , which may represent atelectasis or aspiration in the appropriate clinical setting . No substantial pleural effusion . There is no pneumothorax . Heart size is mild to moderately enlarged . Aorta is calcified and slightly unfolded . No acute osseous abnormalities identified . Severe right glenohumeral joint osteoarthritis noted . Rounded lucency projecting over the left cardiophrenic region raises the possibility of a small hiatal hernia .
    OUTPUT:
