A rare cause of exophthalmia: Osteoblastoma of the frontal sinus

Abstract

Osteoblastoma is a rare benign tumor arising predominantly in the vertebrae or long tubular bones. Its naso-sinusian origin is rare and can be responsible for ophthalmological complications [1].We report the case of 19-yeaold patient admitted to the Ophthalmology department for progressive right exophthalmia and ptosis evolving over 8 months.The diagnosis of osteoblastoma was suspected on CT and MRI imaging and then confirmed by the anatomopatological studies. Total surgical excision was performed. Clinical and radiological evolution has been favorable.
