Optic gliomas

      These tumors occur in children, most often in association with neurofibromatosis (NF 1) . They are slow-growing, nonaggressive, and follow a relatively benign course. Imaging studies usually show fusiform enlargement of the optic nerve. They can extend posteriorly through the optic canal to involve the optic chiasm. From there, they can involve either the opposite optic nerve or the optic tracts. Most optic gliomas enhance with contrast infusion, but the enhancement pattern is variable.
