case_images: Imaging findings of chest radiography and treatments over time. (A) Chest radiography reveals consolidation in the right middle lung when symptoms developed. (B) Chest radiography reveals improvement in consolidations in the right middle lung after initiating prednisolone (30 mg/day) treatment. (C) Chest radiography reveals exacerbation of bilateral consolidations despite administration of antibiotics and methylprednisolone (1000 mg/day for 3 days). (D) Chest radiography reveals mild exacerbation of bilateral consolidations after administration of antibiotics. (E) Chest radiography reveals improvement in bilateral consolidations after initiating antimycobacterial therapy. (F) Chest radiography reveals acute exacerbation of bilateral consolidations on day 29 after hospitalization. (G) Chest radiography reveals improvement in bilateral consolidations after administration of methylprednisolone (1000 mg/day for 3 days). (H) Chest radiography reveals improvement in bilateral consolidations before discharge. (I) Chest computed tomography (CT) reveals consolidation in the right upper lobe of the lung when symptoms developed. (J) Chest CT reveals exacerbation of the consolidation in the right upper lobe of the lung and development of new consolidations in other lobes of the lung. (K) Chest CT reveals exacerbation of bilateral consolidations on day 29 after hospitalization. AFB, acid-fast bacilli; M. goodii, Mycobacterium goodii; po, per os; PSL, prednisolone; iv, intravenous.

case_images: Despite administering antibiotics and tapering of the oral prednisolone dose, the consolidations did not improve (Figure 1D). Subsequently, respiratory failure and consolidations on chest radiography improved (Figure 1E). Chest radiography and computed tomography revealed exacerbation of the consolidations (Figure 1F,K), which was considered worsened OP. Subsequently, consolidations on chest radiography and respiratory failure improved (Figure 1G). Subsequently, the oral prednisolone dose was tapered; consolidations did not worsen (Figure 1H).

case_images: Imaging findings of bronchoscopy and pathological findings of transbronchial cryobiopsy. (A) A large amount of purulent sputum is observed in the right bronchus. (B, C) Histopathologically, lightly staining fibroblast plugs filling the alveolar spaces around the bronchi are observed, suggesting an organizing pneumonia pattern. The peribronchiolar region is not sampled, resulting in insufficient evaluation (x200 magnifications; Haematoxylin-eosin staining and Elastica van Gieson staining).
