Hypersensitivity pneumonitis (HP, also known as extrinsic allergic alveolitis [EAA]) is a rare disease which is limited to the lungs and caused by an immunological inflammatory reaction of the lung parenchyma and terminal bronchioli. The first German guideline on the diagnosis and treatment of HP was published in 2024. The imaging method of choice is high-resolution computed tomography (HRCT). Radiologically, a distinction is made between purely inflammatory and fibrotic HP. If there are signs of fibrotic HP in the HRCT, the relation between the extent of inflammation and fibrosis should be determined and given in the report. The prognosis depends significantly on the extent of fibrosis and the proportion of so-called honeycombs.
过敏性肺炎（HP，也称为外源性过敏性肺泡炎 [EAA]）是一种罕见疾病，仅限于肺部，由肺实质和终末细支气管的免疫炎症反应引起。德国首部关于HP诊断和治疗的指南于2024年发布。首选的成像方法是高分辨率计算机断层扫描（HRCT）。在放射学上，可区分单纯炎症性和纤维化性HP。如果HRCT中有纤维化性HP的迹象，应确定炎症和纤维化程度之间的关系并在报告中给出。预后很大程度上取决于纤维化程度和所谓蜂窝状结构的比例。
