Intraosseous hemangioma of the orbit.
Intraosseous hemangiomas of the orbit are very rare tumors. A case of cavernous hemangioma of the superolateral orbital rim is presented. A 45-year-old woman had a 1-year history of progressive swelling in the left lateral brow area. A computed tomography scan showed a well-marginated osteolytic lesion on the frontal bone near the frontozygomatic suture. The lesion was thought to be fibrous dysplasia, and the patient underwent tumor excision. The histological diagnosis was cavernous hemangioma. Cavernous spaces were filled with blood between the bony trabeculae. The spaces were lined by benign flattened endothelium. Intraosseous hemangioma should be suspected when a patient presents with an enlarging mass fixed to bone around the orbit.
