Abstract
Pulmonary aspergillosis mycetoma commonly forms from saprophytic colonization of preexisting pulmonary cavities of Aspergillus fumigatus, the most common saprophytic species of Aspergillus in human disease, producing a fungus ball or a mycetoma.1,2 The most common symptom associated with aspergillosis mycetoma is hemoptysis, seen in up to 70% of patients.1 Bleeding usually occurs from bronchial blood vessels and may be due to local invasion of blood vessels lining the cavity, endotoxins released from the fungus, or mechanical irritation of the exposed vasculature inside the cavity by the rolling fungus ball,3 and may become life threatening.
