Trigeminal schwannoma of the sphenoid sinus – report of a rare entity

Abstract

Schwannomas are common slow growing benign tumors. About 25–45% of all schwannomas arise in the head and neck region. Less than 4% of these tumors are found in sinonasal regions and usually affect nasal ethmoid. There are very few case reports of a schwannoma arising from the sphenoid sinus. We report a case of sphenoid sinus schwannoma treated by microscopic decompression and review the relevant literature.
