CTICasesVV-ECMO Associated Complete Lung Consolidation
Imaging findings
Serial chest radiographs in a patient on venovenous extracorporeal membrane oxygenation (VV-ECMO) show progressive, symmetric loss of lung aeration, culminating in completely non-aerated, consolidated 'white lungs' without major airway obstruction.
Key takeaways
Complete loss of lung aeration ('white lung') is a well-described, benign phenomenon during VV-ECMO. With respiratory support offloaded to the membrane oxygenator, the lungs can collapse, consolidate, and accumulate hydrostatic fluid. This should not be mistaken for progressive pneumonia or mucus plugging.
