Imaging findings
Chest radiograph and chest CT demonstrate diffuse, symmetric, fuzzy, and smudgy centrilobular nodules throughout both lungs with associated interlobular septal thickening, relative basilar sparing, and a normal heart size without evidence of pulmonary hypertension.
Key takeaways
E-cigarette or vaping product use-associated lung injury (EVALI) frequently presents as diffuse centrilobular nodules with a smudgy, ill-defined appearance on CT, indicating airway-centered inflammation rather than a vasculitic process. Prompt diagnosis and treatment with corticosteroids typically lead to rapid clinical and radiographic improvement.
