A case of intraosseous orbital hemangioma is reported to alert surgeons to possible intraoperative hemorrhage during excision of such a lesion. A slowly enlarging mass was excised from the orbital rim of a 49-year-old woman. The clinical diagnosis was not suspected. In retrospect, roentgenographic findings included a focal honeycombed pattern of the zygomatic bone. Surgery was complicated by persistent low-volume bleeding. Histology showed endothelial-lined blood-filled channels within the bone. Intraosseous orbital hemangioma is a rare, benign neoplasm that can often be diagnosed clinically by characteristic roentgenographic findings. Observation should be considered as a therapeutic alternative when the radiographic diagnosis is established and when ocular function is not compromised.
