The interstitial pneumonias are a group of heterogeneous nonneoplastic lung diseases that may be idiopathic or associated with an underlying abnormality. Although they share some features in common, they also exhibit diverse pulmonary manifestations. Imaging plays an essential role in characterizing this group of disorders and can often suggest the diagnosis, though the final interpretation requires a coordinated effort involving the radiologist, pathologist, and clinician. The purpose of this article is to review the imaging features of the interstitial pneumonias according to their histologic patterns and to provide a brief overview of their clinical presentations.
This article reviews the interstitial pneumonias according to their histologic subtypes, including both idiopathic and secondary forms. On completion, the reader should have an improved understanding of the classification of the interstitial pneumonias, associated causes, characteristic imaging features, histologic descriptions, clinical manifestations, and prognoses.
间质性肺炎是一组异质性非肿瘤性肺部疾病，可能是特发性的，也可能与潜在的异常有关。尽管它们有一些共同的特征，但它们也表现出不同的肺部表现。影像学在描述这组疾病方面起着至关重要的作用，通常可以提示诊断，尽管最终的解释需要放射科医生、病理学家和临床医生的共同努力。本文的目的是根据组织病理学模式回顾间质性肺炎的影像学特征，并简要概述其临床表现。
本文根据组织病理学亚型回顾间质性肺炎，包括特发性和继发性。完成后，读者应能更好地理解间质性肺炎的分类、相关病因、特征性影像学特征、组织学描述、临床表现和预后。
