High-flow hemangioblastoma of the orbit.
A 62-year-old Chinese man was found to have a mass in the right superior orbit and mild fullness in right cavernous sinus associated with minimal proptosis. Carotid artery angiography revealed a vascular tumor in the superior orbit with supply from the internal and external carotid arteries. Selective embolization of the feeder vessel was performed before surgical excision of the tumor. Histopathologic examination with light microscopy and immunohistochemistry confirmed the tumor to have characteristics of a hemangioblastoma. Hemangioblastoma involving the orbit is exceedingly uncommon and to date only one such case has been documented in the literature.
