Triple discrete fungus balls of the paranasal sinuses.

Paranasal sinus fungus balls occur usually in single sinus, most frequently the maxillary sinus. Multisinus localization was found only 6% in the largest review of this disease entity. Even multiple sinuses involved, these sinuses were mostly contiguous. Bilateral involvement was rare in the literature. Nevertheless, there has never been a report of three discrete sinus fungus balls in the same patient. This report represents the first case of the paranasal sinus fungus balls presenting in triple discrete sinuses at once.
