  • Title: [Optic nerve gliomas: a study of 11 cases].
    Author: Torres LF, Medeiros BC, Noronha L, Pedroso A, Ramina R.
    Journal: Arq Neuropsiquiatr; 1996 Jun; 54(2):280-3. PubMed ID: 8984986.
    Abstract:
    Optic nerve gliomas may occur alone or as components of neurofibromatosis. They are rare tumors accounting for 2 to 5% of all intracranial tumors and 6% of the intra-orbitary neoplasms. The authors present 11 cases of optic nerve-glioma diagnosed in Curitiba in the last 25 years. Out of these 11 patients there were 10 women and only 1 man. The ages ranged from 3 to 25 years old, and 6 patients were under 15 years. In this series, 27.3% (n = 3) of the cases were associated with neurofibromatosis. Five patients had their tumors restricted to the optic nerve while the others had either extension to the optic chiasm, supra-selar region, frontal or temporal lobe. All the patients had pilocytic astrocytomas.
