X-ray

Chest radiograph

Total white-out of the right hemithorax with tracheal deviation to the right. 

Case Discussion

 CT confirmed total collapse secondary to a T4N3M1 lung tumor.

White out of the hemithorax on CXR has a limited number of causes. The differential diagnosis can be shortened further with one simple observation - the position of the trachea. Is it central, pulled or pushed from the side of opacification?

  • pulled: pneumonectomy, total lung collapse, pulmonary agenesis
  • central: consolidation, mesothelioma
  • pushed: pleural effusion, diaphragmatic hernia
