Discussion (Related Text)
pulmonary eosinophilia is a transient pulmonary process characterized pathologically by pulmonary infiltration with an eosinophilic exudate. Most patients have a history of allergy, most commonly asthma. The characteristic radiographic findings are peripheral, homogeneous, ill-defined areas of airspace opacities that may parallel the chest wall; this latter feature is best appreciated on CT. The opacities have been described as fleeting because there is a tendency for rapid clearing in one area with new involvement in other areas. A dry cough, dyspnea, and peripheral blood eosinophilia are common but are not invariably present. The diagnosis is based on the combination of pulmonary symptoms, blood eosinophilia, and characteristic radiographic findings. Most patients have a self-limiting illness that resolves spontaneously within 4 weeks.
