Aneurysmal bone cysts (ABCs) are benign, fibrosseous, non-neoplastic, osteolytic, and expansile lesions that develop in childhood or early adulthood. We present a review on ABC literature and a rare case of primary ABC in the orbital roof in a 17-year-old girl, with 9 years of follow-up, who had first been operated at a different department with meningioma diagnosis and subtotally excised. Then when the patient was admitted to our clinic, ABC was suspected on MRI and treated by total excision. After the second operation, a meaningful regression in proptosis diagnosis was determined as compared with her previous examination results. The vision level of both the eyes was measured as the highest level by best correction, and proptosis was not seen during her latest inspection. This case showed us the importance of MRI on ABC diagnosis and effectiveness of total excision on treatment.
