Pulmonary aspergillomaFungus ball; Mycetoma; Aspergilloma; Aspergillosis - pulmonary aspergilloma
Pulmonary aspergilloma is a mass caused by a fungal infection. It usually grows in lung cavities. It can also appear in the brain, kidney, or other organs.
Aspergillosis is an infection caused by the fungus aspergillus. Aspergillomas are formed when the fungus grows in a clump in a lung cavity. The cavity is often created by a previous condition. Cavities in the lung may be caused by diseases such as:
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.
You may not have symptoms. When symptoms do develop, they can include:
Exams and Tests
Your health care provider may suspect you have a fungal infection after x-rays of your lungs show the ball of fungus. Other tests that may be done include:
- Biopsy of lung tissue
- Blood test for presence of aspergillus in the body (galactomannan)
- Blood test to detect immune response to aspergillus (specific antibodies for aspergillus)
- Bronchoscopy or bronchoscopy with lavage
- Chest CT
- Sputum culture
Many people never develop symptoms. Often, no treatment is needed, unless you are coughing up blood.
Sometimes, antifungal medicines may be used.
If you have bleeding in the lungs, your provider may inject dye into the blood vessels (angiography) to find the site of bleeding. The bleeding is stopped by either:
- Surgery to remove the aspergilloma
- Procedure that inserts material into the blood vessels (embolization)
The outcome can be good in many people. 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.
Complications of pulmonary aspergilloma may include:
When to Contact a Medical Professional
See your provider if you cough up blood, and mention any other symptoms that have developed.
People who have had related lung infections or who have weakened immune systems should try to avoid environments where the aspergillus fungus is found.
