"Pulmonary aspergillosis is a collective term used to refer to a number of conditions caused by infection with a fungus of the Aspergillus species (usually Aspergillus fumigatus)."
"The various species of Aspergillus are ubiquitous in the environment, and usually do not cause any human pathology, provided the lungs are structurally normal and the host immunity is intact. If either of these is abnormal, then there is the possibility that this otherwise benign fungus may cause pathology."
"In a patient with normal immunity, Aspergillus rarely causes lung disease. Altered immunity, both heightened (hypersensitivity) or reduced (immunocompromised) predisposes to Aspergillus-related lung disease."
"Aspergillus can colonise pre-existing pulmonary cavities, particularly those left behind by pulmonary tuberculosis. In this setting, the fungus grows and, as it is free to move within the cavity, typically takes on a spherical shape, and is known as an aspergilloma. Other cavities that can predispose to aspergilloma include bullae which may be secondary to emphysema."
