Acute eosinophilic pneumonia(AEP) is one of uncommon causes of fatal respiratory failure. Since first reported in 1979, AEP is considered as different disease entity from chronic eosinophilic pneumonia. Recently, consensus is evolving in regard to diagnostic criteria. We experienced a 21-year old male patient presenting typical clinical and radiological characteristics of AEP. Bronchoalveolar lavage showed eosinophilia and transbronchial lung biopsy revealed infiltration of eosinophils and lymphocytes in interstitium and alveoli. This patient completely recovered within three weeks without corticosteroid. We report this case with brief review of literature.
