Clinical syndrome
Typically, individuals who are affected by aspergillomas do not have symptoms related to the infestation. People often co-exist for decades with aspergillomas prior to incidental diagnosis, typically by x-ray or computed tomography. However, a small percentage of aspergillomas invade into the wall of the cavity and can result in bleeding. Thus, the most common symptom of aspergillomas is coughing up blood (hemoptysis). Although this can occasionally be life-threatening, the amount of blood produced is usually inconsequential.
Aspergillomas can form in other body cavities. Aspergillus can form abscesses in the brain, usually in people who are immunocompromised. They can also form within the different sinuses in the face, within the kidneys and urinary system, the ear canal, and on the heart valves.
Diagnosis
The imaging findings are
- Intracavitary mass
- Usually in upper lobes
- Air may surround aspergilloma (Monod sign). This is not to be confused with the Air crescent sign seen with invasive apergillosis
- Moves with changing positions
- Adjacent pleural thickening is common
Treatment
Most cases of aspergilloma do not require treatment. Treatment of diseases which increase the risk of aspergilloma, such as tuberculosis, may help prevent their formation. In cases complicated by severe hemoptysis, surgery may be required to remove the aspergilloma and stop the bleeding. There has been interest in treatment with anti-fungal medications such as itraconazole, but as of 2005, none has been shown to eradicate aspergillomas.
