title: Aneurysmal bone cyst of the orbit.
abstract: We report the case of an aneurysmal bone cyst of the left orbital roof in a 12-year-old boy who presented proptosis of the left eye and painless swelling of the left orbital rim. A 3-cm-large tumor developed in less than 3 months, with first visible signs about 2 months after a minor head injury. Radiologically, the lesion was osteolytic and multicystic. The cyst, filled with hematic fluid, was surgically removed via left frontal craniotomy and a simple curettage with high-speed bur. The patient recovered well and has been in good health throughout 14 months of follow-up.
