Preferred Label : nonspecific interstitial pneumonia;
Definition : Pathology.—NSIP is characterized by a histologic pattern of uniform interstitial involvement
by varying degrees of chronic inflammation or fibrosis. NSIP may be idiopathic or
seen in other settings, including collagen vascular disease, hypersensitivity pneumonitis,
drug-induced lung disease, infection, and immunodeficiency (including human immunodeficiency
virus infection) (5). CT scans.—NSIP has variable thin-section CT appearances: The
most frequent is ground-glass opacities with reticulation, traction bronchiectasis
or bronchiolectasis, and little or no honeycombing (Fig 43). The distribution is usually
basal and subpleural (95). [Fleischner Society];
