A Case of Multiple Discrete Fungus Balls of the Bilateral Paranasal Sinuses

Abstract

Fungus balls of the paranasal sinuses are usually found in only one sinus, most frequently in the maxillary sinus. Multisinus involvement was found only in 6.4% of the largest review of this disease entity. Though fungus ball could be involved in multiple sinuses, these sinuses were mostly contiguous. In addition, bilateral involvement is rare in the literature：only one case of triple discrete fungus balls in a patient has been reported. We recently experienced a rare case of multifocal discrete fungus ball involving the bilateral maxillary sinus and left sphenoid sinus in a 58 year-old female. Therefore, we present this rare case with a brief review of this disease entity. (Korean J Otorhinolaryngol-Head Neck Surg 2009;52:457-60)
