Chronic pulmonary aspergillosis
- Aspergilloma – fungus ball composed of Aspergillus hyphae, fibrin, mucus, and cellular debris; arise in preexisting cavities that become colonized with Aspergillus
- Aspergillus nodule – occur in immunocompetent hosts, may be single or multiple, usually asymptomatic
- Chronic cavitary pulmonary aspergillosis – formation and expansion of one or more pulmonary cavities over months, can become fibrosing
- Chronic necrotizing pulmonary aspergillosis – slowly progressive form of invasive aspergillosis in immunocompromised hosts

- Surgical resection - offered as treatment to prevent or treat life-threatening hemoptysis, generally well tolerated in patients with a single aspergilloma
- Bronchial artery embolization - used in patients with moderate to severe hemoptysis in order to stabilize prior to surgery
- Antifungals - itraconzole and voriconazole are used in patients with symptomatic, chronic pulmonary aspergillosis or may be used before and after surgery for aspergilloma
