    INPUT: PA and lateral views of chest demonstrate extremely low lung volumes which contribute to bibasilar atelectasis .

The heart size is exaggerated given AP view as well as low lung volumes . No free air is noted in the abdomen . A percutaneous biliary drain is seen in the right upper quadrant .
    OUTPUT:
    
Limited study due to the extremely low lung volumes demonstrating bibasilar and subsegmental atelectasis without convincing evidence of pneumonia , but this evaluation is limited .
