Description

A 23-year-old man was admitted with severe hypoxia and diffuse pulmonary infiltrates on chest X-ray film. One month prior to admission, he had had slight fever after a tooth extraction for caries. Three weeks later, he visited another doctor's office because of high fever and dyspnea. Laboratory findings showed leukocytosis in peripheral blood and CRP elevation in serum. Chest X-ray film showed diffuse bilateral infiltration shadows. He was given antibiotics for acute bacterial pneumonia. However, his condition became exacerbated, and dyspnea developed. He was admitted to the intensive care unit in our hospital. Bronchoalveolar lavage (BAL) and transbronchial lung biopsy (TBLB) were performed. The BAL fluid contained 39% eosinophils, 17% lymphocytes, and 44% macrophages. BALF and pathological findings of the lung were compatible with the findings of acute eosinophilic pneumonia. It was suggested that the tooth extraction was related with the pathogenesis of acute eosinophilic pneumonia.
