    Causes, incidence, and risk factors

    Aspergillomas are formed when the fungus aspergillus grows in a clump in a lung cavity, or invades previously healthy tissue, causing an abscess.

    Aspergillus is a common fungus. It grows on dead leaves, stored grain, bird droppings, compost piles, and other decaying vegetation. Cavities in the lung may have been caused by:

    • Coccidioidomycosis
    • Cystic fibrosis
    • Histoplasmosis
    • Lung abscess
    • Lung cancer
    • Sarcoidosis
    • Tuberculosis
