Twenty-nine patients with bronchiolitis obliterans organizing pneumonia (BOOP) in Japan diagnosed by an open lung biopsy were reviewed. A total of 70% of the patients were idiopathic and 2/3 of the remaining were associated with connective tissue disease. All 29 cases of BOOP showed bilateral pulmonary infiltration on chest X-rays. BOOP can be classified based on the chest X-ray findings into three major types, Type I, Type II and unclasSified type. In Type I shadows appear in the lung fields. In Type II abnormal shadows are seen in the bi-basilar peripheral field with the reduction of the lung volume. Cases of Type I showed inflammatory findings more frequently than cases of Type II. Among 29 BOOP patients, two idiopathic cases died.
对日本29例经开胸肺活检确诊为闭塞性细支气管炎伴机化性肺炎（BOOP）的患者进行了回顾性研究。70%的患者为特发性，其余患者中有2/3与结缔组织病相关。所有29例BOOP患者胸部X线均显示双侧肺部浸润。BOOP可根据胸部X线表现分为三种主要类型，即I型、II型和未分类型。I型在肺野出现阴影。II型在双肺基底外周野可见异常阴影，肺容积减小。I型病例比II型病例更常出现炎症表现。在29例BOOP患者中，2例特发性病例死亡。
