Abstract

Hemangioendothelioma is rarely encountered in the orbit. We present a patient with a growing orbital mass for whom surgical excision was planned. Two previous attempts at removing the mass failed due to profuse bleeding. Endovascular embolization was performed before surgery to prevent massive hemorrhage. After embolization, retinal vascular accident (combined central retinal artery and vein occlusion) occurred. However, surgical excision (lateral orbitotomy and transcoronal craniotomy) was successful, and the vision improved postoperatively. Histopathologic examination and immunohistochemistry study confirmed the diagnosis of epithelioid hemangioendothelioma. The combined approach by a team of specialists, including an interventional radiologist performing preoperative embolization of the feeding vessel and joint surgery by a neurosurgeon and oculoplastic surgeon, was the key to the effective treatment of this vascular orbital neoplasm. © 2018 S.
