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
