A 42-year-old woman presented to our hospital with fever and worsening dyspnea. Eight days prior to symptom onset, she inhaled smoke from a fire caused by an exploded mobile battery. Infiltrative shadows were observed in the bilateral lung fields on chest computed tomography scan, and the eosinophil fraction of the bronchoalveolar lavage fluid was elevated to 61.2 %. Therefore, she was diagnosed with acute eosinophilic pneumonia (AEP). Although AEP can be triggered by various inhalants, including tobacco exposure, this is the first reported case of AEP caused by a mobile battery explosion.
一名42岁女性因发热和进行性呼吸困难前来我院就诊。症状出现前8天，她吸入了由爆炸的移动电池引发火灾产生的烟雾。胸部计算机断层扫描显示双侧肺野有浸润性阴影，支气管肺泡灌洗液中嗜酸性粒细胞比例升高至61.2%。因此，她被诊断为急性嗜酸性粒细胞性肺炎（AEP）。尽管AEP可由多种吸入物引发，包括接触烟草，但这是首例由移动电池爆炸引起的AEP报道病例。
