Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: Study is somewhat limited due to patient rotation on the AP view . Low lung volumes are present which accentuates the size of the cardiac silhouette which is likely mildly enlarged . A moderate size hiatal hernia is re - demonstrated . There is crowding of the bronchovascular structures . Streaky opacities in both lung bases may reflect areas of atelectasis but infection is not excluded . No pleural effusion or pneumothorax is seen . Remote left - sided rib fractures are again noted .
    OUTPUT:
    
Low lung volumes . Streaky bibasilar opacities , likely atelectasis but infection is not excluded . Moderate size hiatal hernia .
