case_images: The chest radiographs showed multifocal and patchy distribution of opacities in the periphery of both lung zones (Fig. 1).
case_images: High resolution computer tomography (HRCT) shows bilateral patchy involvement of alveolar consolidation in mainly both lower lobe and focal ground-glass lesion is also noted.

case_images: f2-kjim-12-1-70-13
case_images: High resolutional computed tomographic scan (HRCT) revealed nonsegmental and peribronchial distribution of alveolar consolidation and ground glass attenuation in the subpleural area, predominantly (Fig. 2).
case_images: Low power view shows elongated or serpiginous polypoid plugs of fibroblastic tissue filling air spaces (H-E, x 40).

case_images: The section showed well demarcated areas of fibrosis involving air spaces in patchy distribution (Fig. 3).
case_images: The air spaces and bronchioles were filled with edema and fibrinous exudate and their lining cells were mostly necrotic or sloughed (H-E, x 100).

case_images: Most bronchiolar lumens or air spaces were filled with fibrinous exudate containing granular eosinophilic necrotic cellular debris (Fig. 4).
