CTICasesVaping-Associated Lung Injury
Imaging findings
CT in a young male runner who presented in respiratory failure shows extensive bilateral ground-glass opacities, septal thickening (crazy paving), and basilar consolidation with distinct subpleural sparing, secondary to THC vaping.
Key takeaways
Vaping-associated lung injury (EVALI) frequently presents with diffuse alveolar damage or organizing pneumonia patterns. Subpleural sparing is a helpful radiological sign that, when coupled with a history of e-cigarette or vaping use, points to the diagnosis.
