Two forms are described in this category: allergic fungal sinusitis and sinus mycetoma/ball.

Most commonly, Curvularia lunata,Aspergillus fumigatus, and Bipolaris and Drechslera species cause allergic fungal sinusitis.

A fumigatus and dematiaceous fungi most commonly cause sinus mycetoma.

A study by Lu-Myers et al found that socioeconomic factors differed between patients with allergic fungal rhinosinusitis and those with chronic rhinosinusitis, with the latter tending to be white and older, with a higher income and greater access to primary care. The study, which involved a total of 186 patients (93 patients in each group), also found that patients with allergic fungal rhinosinusitis tended to have greater quantitative serum immunoglobulin E (IgE) levels and higher Lund-Mackay scale scores than did patients with chronic rhinosinusitis.
