Overview
Chest CT scan may be helpful in the diagnosis of aspergillosis. Findings on chest CT scan suggestive of aspergillosis include a well formed cavity, a central soft tissue attenuating oval shaped, well circumscribed mass surrounded by an cresent of air (Monad sign).[1]
CT Scan
- Chest CT scan may be helpful in the diagnosis of aspergillosis.[1]
- Findings on chest CT scan suggestive of aspergilloma include:
- Well formed cavity
- A central soft tissue attenuating oval, well circumscribed mass
- Surrounded by an cresent of air (Monad sign)
- The mass may illustrate mobility as the patients change their position.
- On certain occasion the mass may entirely fill the cavity, thus it takes on the shape of the cavity, loses its mobility, and obliterates the surrounding air crescent.
- Marked enlargement of the bronchial arteries that supply the wall of the adjacent respiratory tracts
- Thickening of the adjacent pleura may be present
- Findings on chest CT scan suggestive of allergic bronchopulmonary aspergillosis include:[2]
- Fleeting pulmonary alveolar opacities
- Centrilobular nodular opacities representing dilated and opacified bronchioles
- Bronchiectasis
- Bronchial wall thickening
- Honey comb appearance
