BackgroundOrbital lymphaticovenous malformations (LVMs) are congenital vascular lesions that are typically infiltrative in nature. There have been reports of orbital LVMs extending intracranially through orbital fissures, but there have been no reports of intradural extension.Case DescriptionWe report the first case of orbital LVM extending intradurally through a bony defect in the medial orbital roof. A modified orbitozygomatic approach was used to successfully obliterate this lesion. Neurosurgical and ophthalmologic collaboration was used in the surgical management of this case.ConclusionsThis case highlights the importance of an interdisciplinary approach when managing infiltrative orbital LVMs, as both ophthalmologic and neurosurgical expertise were critical in the success of the surgery.
