a–c Coronal enhanced CT images through the anterior a and posterior b lungs show multifocal ground-glass opacity in the bilateral anterior upper lobes; note conspicuous subpleural sparing (arrowheads) affecting the peripheral right lower and medial left basal lung. The posterior lungs b show more pronounced consolidation with developing organization, evidenced by the mild architectural distortion and the band-like nature of the consolidation (arrows) distributed along the bronchi. Coronal maximum intensity projected unenhanced computed tomography c in a different EVALI patient shows diffusely distributed, small, centrilobular ground-glass opacity nodules (arrowheads) typical of a non-fibrotic hypersensitivity pneumonitis pattern
