  Olfactory Neuroblastoma (ONB) is a rare tumor accounting for 3% of all intranasal tumours and its incidence is 0.4 cases per million in the general population. Although it is a rare tumor, it has the potential for aggressive growth and the propensity for regional metastasis. Usually, it presents late due to its indolent course and lack of specific symptoms. It has a bimodal distribution with peak of incidence in second and third decade of life and later in sixth and seventh decade with no gender preponderance. The commonest symptom is nasal obstruction and the commonest site is Cribriform plate and olfactory part of nasal septum. Our case was a 51 years old male who was diagnosed as ONB originating from a very rare site of Sphenoid sinus floor.
