CTICasesVaping-Associated Lung Injury (EVALI)
Imaging findings
CT chest shows diffuse, airway-centric, and bronchiole-centric ground-glass opacities in both lungs, in a 49-year-old male who presented with cough, dyspnea, and fever. The patient had a history of vaping THC/marijuana, and infectious workup was negative.
Key takeaways
E-cigarette or vaping product use-associated lung injury (EVALI) frequently presents with acute respiratory symptoms and fever, mimicking COVID-19 or bacterial pneumonia. The CT findings typically include diffuse ground-glass opacities, which can be airway-centric. Rapid clinical improvement is seen with corticosteroid therapy.
