Abstract

Optic nerve sheath meningiomas (ONSMs) are benign neoplasms originating from the arachnoid cap cells located in the dural sheath surrounding the orbital or intracanalicular portion of the optic nerve. Multiple meningiomas have most commonly been found to be associated with neurofibromatosis type 2 (NF2). Although optic nerve sheath meningiomas are benign and slow growing, they tend to cause severe vision loss at later stages. Patients with meningiomas at one site should be screened for meningiomas at other locations and also for the presence of neurocutaneous stigmata.
