Optic nerve sheath meningiomas are rare ( incidence: – 2% of all orbital tumors), benign neoplasms originating from meningothelial cells of the meninges surrounding the optic nerve. Here we report the case of a 40 year old female who presented with loss of vision, drooping of eyelids, squinting and proptosis of left eye. On examination : she had Left eye – no perception of light, total ophthalmoplegia with inferior dystopia, proptosis, fundus examination showed optic atrophy with sclerosed blood vessels. Associated left LMN facial palsy was also present. Other eye was within normal limits. MRI brain showed moderately enhancing left orbital extraconal mass lesion with intracranial extension to temporal fossa and cavernous sinus involvement. Neurosurgery reference was given.
