A 51-year-old man presented with fever and fatigue after 3.5 months of antituberculosis therapy. High-resolution computed tomography of his chest revealed new ground-glass opacities and poorly defined centrilobular nodules. He had undergone catechin inhalation for 1 month. We diagnosed hypersensitivity pneumonitis (HP) based on the clinical course, bronchoscopy and a challenge test. Cases of HP due to inhalation of extracted catechin powder are rare. Although it has many known positive attributes, it is necessary to be aware that catechin can cause HP.
一位 51 岁男性，在接受抗结核治疗 3.5 个月后出现发热和乏力。胸部高分辨率 CT 显示新的磨玻璃影和边界不清的小叶中心结节。他曾接受儿茶素吸入治疗 1 个月。根据临床经过、支气管镜检查和激发试验，我们诊断为过敏性肺炎（HP）。吸入儿茶素提取物粉末引起的 HP 病例较为罕见。尽管儿茶素有许多已知的有益属性，但仍需注意其可能引发 HP。
