Chest CT (Figure 1a) showed discrete reticulations and ground-glass opacities (GGOs) in the lower lobes. A follow-up chest CT two months later showed more extensive reticulations, septal thickening, consolidation and GGOs (Figure 1b). Chest CT revealed multiple pneumatoceles of varying sizes, a pneumomediastinum and an increase of air-space opacities and reticulations (Figure 1c-d). Chest CT revealed a bilateral pneumothorax and left-sided tension pneumothorax (Figure 1e). One month later there was complete regression of the consolidation and pneumatoceles on chest CT; however, some GGOs and evidence of fibrosis persisted (Figure 1f).
