Limkunacul C Chronic eosinophilic pneumonia (CEP) is a disorder, characterized by a history of pneu-
monia (> 2 months) and eosinophilic pulmonary infiltration without any organic causes. We des-
cribe a 28-year-old woman who presented with cough, dyspnea and fever for 2 months. She was
diagnosed with mild asthma and allergic rhinitis 2 years before being diagnosed with CEP. For a
period of 9 months she took no medication. Her chest roentgenogram at this admission revealed
patchy infiltration in both upper lung fields. Laboratory data revealed blood eosinophilia
(4,284 /mm3
),
and her serum lgE was mildly elevated (245.8 IU/ml). A computerized tomography
of the chest did not show bronchiectasis. CEP was diagnosed from significant eosinophilia in
bronchoalveolar larvage fluid and transbronchial biopsy revealed eosinophilic infiltration without
any demonstrable infectious agent. The patient was treated with prednisolone 45 mg/day. Her
symptoms disappeared and her chest roentgenogram showed nearly complete resolution in 2 and
4 days, consecutively.
