Optic nerve Schwannoma is a very rare tumour described in literature. The rarity of this tumour is due to the fact that the optic nerve is myelinated by oligodendrocytes. We present a case of an ancient optic nerve schwannoma in a 16 year old girl who presented to the clinic with right sided proptosis and bilateral loss of vision. She underwent complete excision of the tumour via a craniotomy and histopathology was confirmatory. The various theories explaining the origin of this tumour are discussed along with surgical nuances of removing this tumour. The importance of taking every precaution to preserve vision and avoiding imaging confusion in patients with von Recklinghausen syndrome is also discussed. Only 6 cases of optic nerve schwannomas are described in literature while none have been described in a patient with NF 1.
视神经施万细胞瘤是文献中描述的一种非常罕见的肿瘤。这种肿瘤罕见的原因在于视神经由少突胶质细胞形成髓鞘。我们报告一例16岁女孩的陈旧性视神经施万细胞瘤病例，该女孩因右侧眼球突出和双侧视力丧失就诊于诊所。她通过开颅手术进行了肿瘤全切，组织病理学检查确诊。文中讨论了关于该肿瘤起源的各种理论以及切除此肿瘤的手术细节。还讨论了在患有冯·雷克林豪森综合征的患者中采取一切预防措施以保护视力并避免影像学混淆的重要性。文献中仅描述了6例视神经施万细胞瘤病例，而在1型神经纤维瘤病患者中尚未见相关描述。
