Wyburn-Mason Syndrome

Abstract
Two patients with unilateral optic atrophy had both suprasellar and intraorbital arteriovenous malformations. The first had associated vascular lesions of the ipsilateral mandible and maxilla, while the second had an ipsilateral facial vascular lesion. To our knowledge, these are the first reported cases of the Wyburn-Mason syndrome in which retinal arteriovenous malformations are absent despite extensive intraorbital involvement with the malformation.
