CTICasesVaping-Associated Lung Injury
Imaging findings
CT chest shows progressive, diffuse interlobular septal thickening and subtle ground-glass opacities with subpleural sparing, which remained stable over one year. A follow-up CT after the patient ceased vaping shows complete resolution.
Key takeaways
E-cigarette or vaping product use-associated lung injury (EVALI) can present with a wide spectrum of radiographic appearances, including subacute/chronic patterns of interstitial lung injury like septal thickening. Clinicians should ask about vaping history in patients presenting with unclassifiable interstitial patterns that resolve after vaping cessation.
