The purpose of this article is to alert clinicians to a new pathogenic fungus of the paranasal sinuses called Exserohilum rostratum. Exserohilum species are one of the etiologic agents of phaeohyphomycosis, a constellation of entities caused by dematiaceous fungi. This class of fungal sinus infection has emerged only in the past decade; it occurs primarily in immunocompetent individuals and produces a tenacious, progressive pansinusitis. To our knowledge, this study describes the first case of multiple intracranial mucoceles secondary to E rostratum. The diagnostic workup includes computed tomography and magnetic resonance imaging followed by direct microscopic examination of tissue biopsy specimens. A craniotomy followed by a bilateral external ethmoidectomy was necessary for complete extirpation of the infected mucoceles. Aggressive surgical management of this mycotic infection is described.
