Complete White-Out

complete white-out CXR

‘Complete White Out’ on the 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 (this case):
-Pneumonectomy
-Total Lung Collapse
-Pulmonary Agenesis

Central:
-Consolidation
-Mesothelioma

Pushed:
-Pleural effusion
-Diphragmatic hernia

CT confirmed total collapse secondary to a T4N3M1 lung tumour.
