Abstract
|
|
|
|
Olfactory neuroblastoma is a relatively uncommon malignant tumor originating from neuroectoderm and it usually arises from the superior portion of the nasal cavity, such as superior turbinate, superior part of septum, or cribriform plate. Cases of olfactory neuroblastoma from sphenoid sinus, in which olfactory epithelium rarely exists, have been rarely reported. Although nasal obstruction and epistaxis are the most common presenting symptoms of olfatory neroblastoma, our patient presented with headache and dizziness. The most common cause of isolated sphenoid lesion is inflammation, but the possibility of tumorous conditions should not be excluded without thorough evaluation. The authors experienced a rare case of olfactory neuroblastoma from sphenoid sinus that had been confused as isolated sphenoid sinusitis. So we report our unusual case with a brief review of literature.
