Rarely, sinusitis is caused by fungi. Fungal sinusitis (eg, allergic fungal sinusitis) may appear similar to lower airway disorder and allergic bronchopulmonary aspergillosis.

Fungal agents associated with this condition include Aspergillus and Alternaria species. Bipolaris and Curvularia species are the most common fungi recovered in allergic fungal sinusitis, accounting for 60% and 20%, respectively, in most studies. Curvularia species is occasionally reported as the most common causative organism in the deep southern United States.
