title: Isolated esthesioneuroblastoma of sphenoid sinus.
abstract: Esthesioneuroblastoma is a rare neuroendocrine tumor that arises from the olfactory epithelium and accounts for approximately 3% of all intranasal tumors. The tumor involvement in the nasal cavity with extension to paranasal sinuses, orbit, and anterior cranial fossa, is reported in the literature. In this report, we present an interesting case of isolated sphenoid sinus esthesioneuroblastoma, which is the first case to be reported in the literature, and discuss the pathology, clinical manifestations, and various treatment options for this tumor.
