Preferred Label : organizing pneumonia;
Definition : Pathology.—Organizing pneumonia manifests as a histologic pattern characterized by
loose plugs of connective tissue in the airspaces and distal airways. Interstitial
inflammation and fibrosis are minimal or absent. Cryptogenic organizing pneumonia,
or COP, is a distinctive clinical disorder among the idiopathic interstitial pneumonias
(5), but the histologic pattern of organizing pneumonia is encountered in many different
situations, including pulmonary infection, hypersensitivity pneumonitis, and collagen
vascular diseases. Radiographs and CT scans.—Airspace consolidation is the cardinal
feature of organizing pneumonia on chest radiographs and CT scans. In COP, the distribution
is typically subpleural and basal (Fig 45) and sometimes bronchocentric (96). Other
manifestations of organizing pneumonia include ground-glass opacity, tree-in-bud pattern,
and nodular opacities (37). [Fleischner Society];
