Acute eosinophilic pneumonia with fine nodular shadows.
A 19-year-old woman presented with acute onset of cough and dyspnea. She started smoking two weeks before the appearance of symptoms. On admission, arterial blood gas analysis on room air breathing revealed PaO2 55 Torr. Chest roentgenogram and high resolution computed tomograms showed localized fine nodular shadows at the right lower lung field. Bronchoalveolar lavage fluid revealed a high eosinophil count. Eosinophil infiltration was also observed in transbronchial lung biopsy specimens. The final diagnosis was acute eosinophilic pneumonia (AEP). Although few reports have demonstrated diffuse fine nodular shadows in AEP, localized fine nodular shadows on chest roentgenogram and CT may sometimes be the sign of AEP especially in the early phase of the clinical course.
