Aspergilloma
A aspergilloma, also known as pulmonary aspergillosis, is a human disease of the lung caused by the colonization of a by a fungus of the genus Aspergillus, most commonly Aspergillus fumigatus. The spores are transmitted through the air and are not contagious between individuals. It is a frequent complication of tuberculous cavities, which are themselves the primary sequelae of pulmonary , and correspond to localized lung destruction. The cavities of pulmonary tubercles are poorly equipped to defend against Aspergillus , allowing the fungus to proliferate and form a pseudo-tumor that partially fills the cavity. It is estimated that more than 370,000 people worldwide develop an aspergilloma each year.
