CTICasesEVALI
Imaging findings
CT chest shows geographic, subpleural-sparing ground-glass opacities, septal thickening, and centrilobular tree-in-bud nodular opacities, representing acute bronchiolitis and organizing pneumonia in a young patient with a history of e-cigarette (vaping) use.
Key takeaways
E-cigarette or vaping product use-associated lung injury (EVALI) classically manifests on CT with ground-glass opacities, organizing pneumonia, or acute interstitial pneumonia patterns, often sparing the immediate subpleural lung. Tree-in-bud opacities can represent vaping-induced bronchiolar injury.
