Acute eosinophilic pneumonia

Abstract

Pathophysiology of AEP has been under discussion since the first description of this disease by Allen and his colleagues in 1989. Many factors have been incriminated as a cause of this disease. Cigarette smoking is one of those factors suggested by many investigators based on the finding that some young patients have developed AEP after they began to smoke and showed positive results for provocation tests. Imaging manifestations of AEP consistent with pulmonary edema, including interlobular septal thickening, patchy areas of air space consolidation or ground-glass attenuation, and pleural effusion.
