Two weeks after the initiation of prednisolone treatment, the consolidations seen on the chest CT scan were improved, although some cavity lesions (pneumatoceles) developed in the right lung (Fig. 4A). Two months after the corticosteroid therapy commencement, the consolidations and pneumatoceles had disappeared, and only pleural and interlobular septal thickening remained (Fig. 4B).
