Intraosseous hemangioma at the left lateral canthus: a case report
A 56-year-old Chinese woman presented with a 7-year history of a progressive, painless swelling at the left lateral canthus. Contrast-enhanced computed tomography (CT) of the orbit revealed a hypodense lesion of 1.4 cm at the anterior aspect of the left zygomatic arch. A radiological diagnosis of fibrous dysplasia was made. Debulking of the left lateral wall was performed. Intraoperatively, a diamond burr was used to smooth the surface and resulted in moderate bleeding, which was uncommon for fibrous dysplasia. Hemostasis was achieved with bone wax and direct compression. The pathological diagnosis was an intraosseous hemangioma.
