Pulmonary aspergillosis: a spectrum of disease.
Although many species of the fungus Aspergillus have been identified, the most common human pathogen is A. fumigatus, which has a worldwide distribution. Although any organ may become infected, pulmonary aspergillosis is the most common manifestation. The spectrum of pulmonary aspergillosis includes saprophytic aspergillomas, allergic bronchopulmonary aspergillosis, chronic necrotizing aspergillosis, and invasive aspergillosis. Immune status of the host, and the presence of underlying lung disease are important in determining the type of pulmonary involvement. Thus, the radiographic findings are variable. This article reviews the various manifestations of pulmonary aspergillosis, including the immune status of the patient, the presence of underlying lung disease, and the radiographic appearance of the different entities.
