CTICasesRe-expansion Pulmonary Edema
Imaging findings
Chest radiograph and CT show rapid development of dense, unilateral, consolidative airspace opacities in the right lung immediately following the evacuation of a large, chronic pneumothorax.
Key takeaways
Re-expansion pulmonary edema is a non-cardiogenic injury that occurs when a chronically collapsed lung is rapidly re-expanded. The pathophysiology involves endothelial injury, microvascular permeability, and alveolar flooding, and treatment is supportive.
