Study Notes
Aspergillus Fumigatus
- Aspergillus has acute branching with septations
Risk Factors and Associations
- Peanuts are associated with aflatoxins produced by Aspergillus flavus
- Aflatoxins are also associated with grains
- Hepatocellular carcinoma is associated with Aspergillus infection
Infections and Clinical Features
- Allergic bronchopulmonary aspergillosis (ABPA) causes wheezing, fever, and migratory pulmonary infiltrate
- Susceptibility to aspergillosis increases with TB cavities
- Aspergillosis can cause aspergillomas, which are gravity-dependent and typically form at the bottom of cavities
Angioinvasive Aspergillosis
- Occurs in patients with neutropenia, often due to leukemia or lymphoma
- Invades blood vessels and surrounding tissues
- Can cause kidney failure, endocarditis, and ring-enhancing lesions in the brain
- Can invade nasal sinuses
Treatment
- Voriconazole is used for less serious infections
- Amphotericin B is used for angioinvasive disease
Diagnosis
- Histology is the best way to identify Aspergillus, characterized by 45-degree branching septae
