Acute eosinophilic pneumonia caused by an exploding mobile battery: A case report

Abstract

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.
