Intraosseous Hemangioma in the Periorbital Region Treated With Surgical Resection and Reconstruction.

Intraosseous hemangioma is a rare benign vascular tumor accounting for <1% of all bone tumors. This condition most commonly arises in the vertebrae and skull, while occurrence in the periorbital region is uncommon. We report 2 cases of intraosseous hemangioma arising in the nasal bone and zygomatic bone, respectively. Both patients were middle-aged females who presented with slowly progressive swelling. Computed tomography (CT) of Case 1 showed a characteristic sunray burst appearance, while Case 2 demonstrated a polka-dot sign. Both cases underwent complete surgical excision with a safety margin and reconstruction using autologous costal cartilage and cancellous iliac bone graft in nasal bone and zygomatic defects, respectively. Histopathologic examination confirmed cavernous hemangioma in both cases. No recurrence or significant complications were observed during follow-up. These findings suggest that surgical resection with appropriate reconstruction is an effective treatment for intraosseous hemangioma in the periorbital region.
