Abstract

PURPOSE
Fibrous dysplasia is an uncommon, benign bony disease of unknown etiology which typically presents in children or young adults. Fibrous dysplasia of the head mainly affects the maxillary bone and rarely affects the orbit. The authors report a case of fibrous dysplasia with secondary cystic change of the orbit that was incidentally discovered in an adult. Literature review is also included. METHODS: A 49-year-old man presented for evaluation of tumor of the right orbit. The orbital tumor was found incidentally on a brain MRI, which was carried out to evaluate the patient's symptom of dizziness. Computed tomography showed a cystic mass-like lesion in the right orbit with bony erosion. Tumor excision with lateral orbitotomy was performed. RESULTS: The pathologic result was consistent with the diagnosis of fibrous dysplasia with secondary cystic change.

Key Words: Fibrous dysplasia;Orbit;Secondary cystic change
