Such cases, termed acute eosinophilic pneumonia (AEP), may not be associated with the peripheral blood eosinophilia typical of chronic eosinophilic pneumonia
. (7) Both AEP and EP may be associated with underlying etiologies such as toxic inhalation, drug reaction, or infection, particularly with parasites or fungus, or may be idiopathic.
