BACKGROUND:: Allergic fungal sinusitis (AFS) is thought to represent an immunologic response to exposure to dematiaceous fungi. These fungi are known to cause disease more frequently in hot and humid climates and seasons. METHODS:: Three patients presented with unusual manifestations of fungal disease after exposure to environments recently affected by hurricanes. RESULTS:: Two patients had AFS, 1 with gradual painless visual loss from an AFS mass extending into the suprasellar region and 1 with orbital apex syndrome. Another patient had invasive fungal disease and developed orbital apex syndrome. CONCLUSIONS:: These cases underscore the importance of clinical recognition of fungal disease in patients with sinus, orbital, or skull base involvement as well as its potential for causing permanent visual loss. This report suggests a potential association between fungal disease and tropical storm exposure.
