We report a case of BOOP-type pneumonitis after postoperative irradiation for lung cancer. A 60-year-old woman with adenocarcinoma in the right lung underwent lobectomy followed by radiotherapy of 50.4 Gy. After a shadow of typical radiation pneumonitis was resolved in the irradiated site, two relapses, in which migratory infiltrative shadows appeared outside the radiation field, occurred at 6 and 12 months after the completion of radiotherapy. These shadows disappeared spontaneously at 10 and 18 months after the completion of radiotherapy. The radiological findings and clinical course suggested that BOOP-type pneumonitis was the most likely diagnosis for these lesions. This type of lung damage after radiotherapy of the thoracic region should be identified and properly treated.
我们报告一例肺癌术后放疗后发生的闭塞性细支气管炎伴机化性肺炎（BOOP）型肺炎。一名60岁右肺腺癌女性患者接受了肺叶切除术，随后接受了50.4 Gy的放射治疗。在照射部位典型的放射性肺炎阴影消散后，放疗结束后6个月和12个月出现了两次复发，表现为放射野外出现游走性浸润阴影。这些阴影在放疗结束后10个月和18个月时自行消失。放射学表现和临床病程提示这些病变最可能的诊断为BOOP型肺炎。胸部放疗后这种类型的肺损伤应予以识别并进行适当治疗。
