Pulmonary aspergilloma is a mass caused by a fungal infection that usually grows in pre-existing lung cavities. It can also appear in the brain, kidney, or other organs.
Alternative Names
Fungus ball; Mycetoma; Aspergilloma
Causes, incidence, and risk factors
Aspergillomas are formed when the fungus Aspergillus grows in a clump in a pre-existing pulmonary (lung) cavity or when the organism 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. Pre-existing cavities in the lung may have been caused by a previous infection, such as histoplasmosis , tuberculosis , lung abscess , or by cystic fibrosis , sarcoidosis , or previous lung cancer . See also aspergillosis .
Treatment
The most effective therapy is surgical removal of the growth. If life-threatening bleeding occurs, emergency surgery may be the only option. In some cases, angiography (injection of dye into the blood vessels) may be used to locate the site of bleeding, which can allow the physician to stop it. Occasionally, antifungal medications such as itraconazole and amphotericin B can be used. Sometimes these antifungals are added if complete surgical removal is not possible, or if the Aspergillus infection has expanded beyond the aspergilloma.
Expectations (prognosis)
The outcome can be good, if complete surgical removal of the abnormal lung is feasible.
Complications
Progressive difficulty breathing
Massive bleeding from the lung Spread of the infection (see acute invasive aspergillosis )
Calling your health care provider
See your health care provider if coughing up blood occurs, and mention any other symptoms that have developed.
Prevention
People who have had related lung infections or who have weakened immune systems should try to avoid environments where the Aspergillus fungus is found.
