High-resolution computed tomography (HRCT) of the chest showed diffuse ground-glass opacities with ill-defined centrilobular nodules throughout both lungs with upper lobe predominance, without cavitation, bronchiectasis, or tree-in-bud opacities (Fig. 1A). Repeat chest HRCT after steroid treatment demonstrated complete resolution of the abnormalities (Fig. 1B).
