The prognosis for fungus in the lungs, or pulmonary aspergilloma, is positive in many cases. The condition rarely requires treatment, but if it leads to severe and potentially fatal bleeding, surgery may be necessary. Surgery may cause complications that significantly affect the prognosis, according to MedlinePlus.
Pulmonary aspergilloma develops in individuals with a weakened immune system who are exposed to the Aspergillus fumigatus fungus, explains MedlinePlus. Aspergillus fumigatus grows on compost heaps, bird droppings and decaying plants. Pulmonary aspergilloma may develop on healthy lung tissue or within a lung. The causes of lung cavities include sarcoidosis, lung cancer, histoplasmosis, lung abscess and tuberculosis.
Aspergilloma is one form of aspergillosis, the condition caused by exposure to the Aspergillus fungus, and its other forms include invasive aspergillosis and allergic bronchopulmonary aspergillosis, states Healthline. In aspergilloma sufferers, a growth made up of white blood cells, blood clots and fungus forms in the lungs but rarely spreads to other organs. Invasive aspergillosis is an infection that spreads from the lungs to other organs, such as the kidneys or brain, and can be a life-threatening condition in individuals with a weak immune system. Allergic bronchopulmonary aspergillosis is an allergic reaction that leads to responses including wheezing and coughing. The risk of developing any type of aspergillosis may increase as a result of taking certain medications.
