case_images: High-resolution computed tomography (HRCT) chest showed peripherally based patchy, subsegmental lesions of the upper lobe and left lower lobe (Figures 2 and 3).

case_images: Transbronchial lung biopsy was performed, and histology (Figures 4 and 5) showed air space consolidation with fibrinous exudation and polymorph and macrophage infiltration, along with polypoidal proteinous layer in the alveolar spaces composed of granulation tissue, with alveolar septa showing moderately dense chronic inflammatory infiltrates (Masson bodies), all were suggestive of cryptogenic organizing pneumonia (BOOP).
case_images: High-power examination shows Masson bodies that are rounded nodules of granulation tissue in alveolar spaces.
