    INPUT: The lungs are well expanded and show mild interstitial opacities . The evaluation is complicated due to patient rotation . Within these limitations , the cardiomediastinal silhouette is unchanged with aortic calcifications . No definite evidence of aortic dilation is noted . The cardiac silhouette , hilar contours and pleural surfaces are normal . No pleural effusion or pneumothorax is present . Moderately severe glenohumeral osteoarthritis with joint space narrowing is partially imaged on the right . No definite rib fractures are noted , although if rib fractures are clinical concern , then dedicated rib series with a marker at the site of pain is recommended .
    OUTPUT:
    
1 . Mild interstitial edema . No definite evidence of rib fractures . 2 . Moderately severe right glenohumeral osteoarthritis .
