Aspergillomas are formed when the fungus Aspergillus grows in a clump in a lung cavity, or invades healthy tissue, causing an abscess. The most common species of fungus that causes disease in humans is Aspergillus fumigatus.
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 be caused by:
Many patients never develop symptoms. Often, no treatment is needed, unless you are coughing up blood.
Occasionally, antifungal medications may be used.
If you have bleeding in the lungs, your doctor may inject dye into the blood vessels (angiography) to find the site of bleeding. The bleeding is stopped by shooting tiny pellets into the bleeding vessel.
Surgery is often the only choice if there is life-threatening bleeding.
The outcome can be good in many patients. However, it depends on the severity of the condition and your overall health.
Surgery may be very successful in some cases, but it is complex and can have a high risk of serious complications.
