Malignant fungal infection of the cavernous sinus: case report.

Intracranial spread of fungal infection is a life-threatening condition that usually affects immunocompromised patients. Here the authors present a case of biopsy-proven Aspergillus fumigatus infection of the paranasal sinuses in an immunocompetent patient with documented spread to the orbit, cavernous sinus, and petrous apex despite medical antifungal treatment. As a life-saving treatment, cavernous sinus resection with external carotid artery-middle cerebral artery bypass was performed. The authors discuss the literature regarding the intracranial spread of paranasal sinus fungal infections in immunocompetent patients and management strategies.
