Abstract

Olfactory neuroblastoma is a rare malignant tumor of the nasal cavity arising from the olfactory neuroepithelium. It usually present as a polypoid mass in the superior nasal cavity including the cribriform plate, superior turbinate, and superior portion of nasal septum. The development of olfactory neuroblastoma outside of the region, in which olfactory epithelium exists, is exceedingly rare. In this report, we present an interesting case of an isolated sphenoid sinus olfactory neuroblastoma with a brief review of the literature.
