Her chest CT showed bronchiectasis and right sided tree-in-bud opacities (Figures 2(a) and 2(b)). Repeat chest CT eight weeks later showed waxing and waning parenchymal opacities with improvement in the right upper lobe but new nodular opacities involving the right middle lobe and lingula (Figure 2(c)). She improved clinically with radiographic resolution of disease (Figures 2(d) and 2(e)).
