ABSTRACT
This case concerns a 48-year-old, male non-smoker who presented to our department with a chief complaint of dyspnea on exertion. Fever and hypoxemia were observed, and computed tomography showed diffuse ground-glass appearance and consolidation in all lung fields. Bronchoalveolar lavage showed an increased number of eosinophil, and a drug-induced lymphocyte stimulation test (DLST) was positive for Euglena gracilis (supplement), leading to the diagnosis of drug-induced lung injury. Euglena gracilis was discontinued, and methylprednisolone (mPSL) 1,000 mg/day for 3 days was administered. The clinical symptoms and laboratory findings rapidly improved.
