Discussion of Aspergilloma
- AKA mycetoma
- "Fungus ball" consisting of fungus, mucus, and inflammatory cells.
- Grows within a pre-existing cavity (i.e. cavity from tuberculosis or bulla from emphysema).
- Commonly a solitary lesion that is located in the upper lobes.
- Treatment is surgical resection and intracavitary antifungal agents.
 Imaging Findings for Aspergilloma
- 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
