| الوصف: | Os gliomas do nervo óptico podem apresentar-se esporadicamente ou como componentes da neurofibromatose. São neoplasias raras, correspondendo a 2 a 5% dos tumores intracranianos e cerca de 6% dos tumores intra-orbitários. No presente estudo, analisamos 11 casos de glioma de nervo óptico diagnosticados em Curitiba num período de 25 anos, sendo 10 pacientes do sexo feminino e 1 do sexo masculino. As idades variaram de 3 a 25 anos; 6 pacientes apresentavam idades inferiores a 15 anos. Dos casos desta série, 27,3% (n=3) apresentavam associação com neurofibromatose. Quanto à localização dos tumores, em 5 pacientes a lesão estava restrita ao nervo óptico e no restante havia extensão para o quiasma óptico, região supra-selar, lobo frontal ou temporal. Todos os pacientes tinham astrocitoma pilocítico.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. |
