A 34-year-old male presenting with electronic cigarette or vaping-associated lung injury with acute eosinophilic pneumonia.. A. Initial chest radiograph shows diffuse ill-defined haziness with multifocal Kerley B lines (arrows) in both lungs, especially in both lower lobes, and bilateral pleural effusion is observed without cardiomegaly.. B. Axial and coronal CT images (mid-lung axial, lower-lung axial, and coronal views respectively) demonstrate multiple patchy consolidations, ill-defined ground-glass opacities and diffuse interlobular septal thickening in both lungs with lower lobe predominance and peripheral distribution. Small amount of pericardial effusion (not shown) and bilateral pleural effusion was present as well.. C. Follow-up chest radiograph, which was taken after two weeks of steroid therapy and cessation of vaping, demonstrates significant improvement of previous bilateral haziness, Kerley B lines and bilateral pleural effusion.

B lines was observed in both lungs, especially in both lower lobes. Bilateral pleural effusion was also seen (Fig. 1A). Small amount of pericardial effusion and bilateral pleural effusion was present as well (Fig. 1B). With the initiation of steroid treatment and cessation of vaping, the patient's diffuse ill-defined bilateral haziness decreased on follow-up chest radiographs (Fig. 1C).
