Organising pneumonia (OP) is currently recognised as a nonspecific lung injury response that is associated with a variety of imaging patterns obtained with high-resolution computed tomography (HRCT) of the chest and is characterised histopathologically by the presence of inflammatory cells and a connective tissue matrix within distal airspaces of the lungs. OP is associated with many conditions that include connective tissue disorders, various infections, drug reactions, hypersensitivity pneumonitis and aspiration. When OP cannot be linked to an associated condition and appears to be idiopathic, it is termed cryptogenic organising pneumonia.

隐源性机化性肺炎：目前对一种神秘肺部疾病的理解

机化性肺炎 (OP) 目前被认为是一种非特异性肺损伤反应，与通过胸部高分辨率计算机断层扫描 (HRCT) 获得的多种成像模式相关，其组织病理学特征为炎症细胞和结缔组织的存在肺远端气腔内的基质。OP 与许多疾病有关，包括结缔组织疾病、各种感染、药物反应、过敏性肺炎和吸入。当 OP 不能与相关疾病联系起来并且似乎是特发性时，它被称为隐源性机化性肺炎。
