A neonate with Löffler syndrome

Abstract

We report a neonate-boy with pulmonary infiltrates and peripheral blood eosinophilia. He was noted to have abnormal pulmonary infiltrates on a chest X-ray film taken on day 8 after birth when he had vomiting. He had not such symptoms as cough or dyspnea. In routine laboratory studies, eosinophilia was noted. Radiographic changes were transient and disappeared by day 25. Eosinophilia was also transient and gradually returned to normal level by 2 months. Löffler syndrome is very rare in neonates and its diagnosis is often made fortuitously likely in this case.
