    INPUT: Left chest wall port this again seen with catheter tip in the right atrium . There are linear bibasilar opacities potentially due to atelectasis . The lungs are otherwise clear . The cardiomediastinal silhouette is within normal limits . The expected contour of the lateral left scapula is not seen and is suspicious for metastatic disease .
    OUTPUT:
    
Linear bibasilar opacities most likely atelectasis although infection is not entirely excluded . Progressive destruction of the left scapula worrisome for metastatic disease .
