Frontal sinus fibrous dysplasia with atypical radiological features: A case report and review of the literature

Objectives: To present a case of frontal sinus fibrous dysplasia with atypical radiological features and to perform a literature review. Case report: A 63 year old gentleman presented to clinic with a one year history of right eye proptosis. CT and MRI were performed and identified a mass filling the frontal sinus and eroding the orbital wall. The patient had a combined endoscopic and open approach to the right frontal sinus with the final diagnosis being fibrous dysplasia. Study design: Case report and literature review. Methods: Systematic literature review was conducted with the review focusing on the radiological features of fibrous dysplasia in the head and neck. Results: Fibrous dysplasia can present in a variety of ways in the head and neck. There are certain features in its radiological appearance that can aid in early identification of the disease, thereby leading to the development of better management plans. In CT scan, the ground glass appearance is the most persistent presentation. While in MRI, the degree of mineralization of the lesion dictates its signal intensity. Keywords: Fibrous dysplasia, Frontal sinus, Orbital erosion, Proptosis
