Abstract

Benign osteoblastoma is a rare tumor of bone, usually confined to the long bones and vertebrae. Its occurrence in the paranasal sinuses is extremely rare. In this article, we report a 31-year-old male patient with benign osteoblastoma in sphenoethmoid region. A pathological mass was detected on axial and coronal plane in computed tomography imaging of the paranasal sinus. The tumor was excised and the pathological diagnosis was reported as benign osteoblastoma. In this article, a rare location of osteoblastoma and its treatment is described.
