title: Endoscopic resection of a venous hemangioma of the optic nerve sheath.
abstract: We describe a case of a venous hemangioma that arose in the optic nerve sheath of the orbital apex in a 28-year-old man who presented with progressive vision loss. To the best of our knowledge, this is the first reported case of a venous hemangioma occurring at this location. A definitive diagnosis and partial excision was achieved via an endoscopic transsphenoethmoid approach with interactive, computer-assisted, frameless stereotactic surgical navigation. The intervention resulted in minimal morbidity, demonstrating yet again that this surgical approach is a safe and effective way to treat lesions of the orbital apex.
