Hemithorax white-out

Complete white-out of a hemithorax on the chest x-ray 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?

Trachea pulled toward the opacified side
Trachea remains central in position
Pushed away from the opacified side
