American Thoracic Society-European Respiratory Society Classification of the Idiopathic Interstitial Pneumonias: Advances in Knowledge since 2002.

摘要: In the updated American Thoracic Society-European Respiratory Society classification of idiopathic interstitial pneumonias (IIPs), major entities have been preserved and grouped into (a) "chronic fibrosing IIPs" (idiopathic pulmonary fibrosis nonspecific pneumonia), (b) "smoking-related (respiratory bronchiolitis-associated lung disease desquamative (c) "acute or subacute (cryptogenic organizing pneumonia acute (d) "rare (lymphoid pleuroparenchymal fibroelastosis). Furthermore, it has acknowledged that a final diagnosis is not always achievable, category "unclassifiable IIP" proposed. The diagnostic interpretation IIPs often challenging because other diseases with known etiology (most notably, connective tissue hypersensitivity pneumonitis) may show similar morphologic patterns. Indeed, more emphasis given to integration clinical, computed tomographic (CT), pathologic findings for multidisciplinary diagnosis. Typical CT-based patterns are associated IIPs, radiologists play an important role in characterization. Optimal CT quality systematic approach both pivotal evaluation IIP. Interobserver variation various encountered issue. It understand longitudinal behavior at serial examinations, especially providing framework cases unclassifiable which histologic cannot be obtained.
