Orbital giant primary osteoma: Case report and literature review

Abstract

Osteoma is a benign, slow-growing bone tumor that primarily affects the jaw and paranasal sinuses. Intraorbital location, whether primary or secondary, is rare. Although it is generally asymptomatic, it can become symptomatic. As it grows, orbital osteoma can cause symptoms due to displacement and compression of the orbital contents posing a risk to vision. This article is a literature review and case report of a large primary orbital osteoma in a 36-year-old woman, initially asymptomatic and later exhibiting a few symptoms despite significant displacement of the orbital structures that the tumor causes. Its handling was controversial for us because we did not have references on the approach we should be taking. To this date, no cases of asymptomatic intraorbital osteomas of this size have ever been published.
