Triple discrete fungus balls of the paranasal sinuses

Paranasal sinus fungus balls occur usually in single sinus, most frequently the maxillary sinus.(1) Multisinus localization was found only 6% in the largest review of this disease entity.(2) Even multiple sinuses involved, these sinuses were mostly contiguous. Bilateral. involvement was rare in the literature.(2-4) 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.
