Optic nerve sheath meningiomas (ONSM) is a rare benign tumor of eye. On having a clinical suspicion, diagnosis is usually established by contrast MRI/CT scan. Here we present a case of 35-year-old female who presented with unilateral total ophthalmoplegia, mild proptosis and progressive decrease of vision. It was later diagnosed as a case of optic nerve sheath meningioma on MR imaging.
