Forms of aspergillosis that affect the sinuses do not usually spread to other parts of the body, states the Centers for Disease Control and Prevention. These include allergic Aspergillus sinusitis, which causes inflammation in the sinuses and has symptoms similar to a sinus infection, and aspergilloma, or a "fungus ball."
Aspergilloma is a collection of Aspergillus fungi in the shape of a ball, according to the Centers for Disease Control and Prevention. It commonly grows in the lungs or the sinuses. Aspergillus is a prevalent mold that is commonly breathed in by people everyday. Individuals who have weakened immune systems or concurrent lung diseases are at greater risk for developing complications due to Aspergillus.
