case_images: HRCT on admission. Chest HRCT image on admission. (A) Diffuse ground glass opacities predominantly in the upper lobes. (B) Infiltration shadows were seen in the bilateral lower lobes. (C) Air trapping was observed in expiratory CT.

case_images: A chest high-resolution CT (HRCT) at admission showed bilateral lower lobe infiltration shadows, diffuse ground glass opacities predominantly in the upper lobes, and air trapping during exhalation CT (Fig. 1).
case_images: Image of patient's house. Wood rot was observedon (A) floor and (B) wall.

case_images: We suspected HP based on the living environment (Fig. 2), including the rotting walls and household items in his room, ground glass opacities predominantly in the upper lobes on chest HRCT, and elevated SP-D value.
case_images: Pathologic findings. Hematoxylin-Eosin Stain in right lower lobe B9b, showing lymphocyte and plasma cell infiltration in the airway center. (A) Weak magnification: 40x, (B) Strong magnification: 200x.

case_images: No obvious granuloma formation was observed (Fig. 3).
case_images: HRCT after 31 days from antigen avoidance test. (A) The ground glass opacities in the bilateral upper lobes were improved. (B) The ground glass opacities in bilateral lower lobes were also improved.

case_images: On HRCT finding, ground glass opacities were mostly improved; however, some reticular shadows remained, suggesting a diagnosis of fibrotic HP caused by Paecilomyces (Fig. 4).
