Superior Sagittal Sinus Invasion by Malignant Glioma: Case Report and Literature Review

Abstract

Anaplastic oligodendrogliomas (AOs) correspond to ∼ 23% of all oligodendrogliomas. They correspond to a tumor with malignant histological characteristics, focal or diffuse, associated with a worse prognosis. In the present case report, we describe the case of a 30-year-old female submitted to resection of a right parietal lesion whose histology showed to be an AO. She underwent complementary treatment with chemotherapy and radiotherapy according to the Roger Stupp protocol. Four years after the initial diagnosis, there was tumor recurrence within the superior sagittal sinus, with no evidence of recurrence elsewhere. In the literature, we have found no similar published case reinforcing the rarity of this condition

Resumo

Oligodendrogliomas anaplásicos correspondem a ∼ 23% de todos os oligodendrogliomas. Eles correspondem a um tumor com características histológicas malignas, focais ou difusas, associadas a um pior prognóstico. Descrevemos aqui o caso de uma mulher de 30 anos de idade submetida à ressecção de uma lesão parietal direita, cuja histologia mostrou ser um oligodendroglioma anaplásico. A paciente foi submetida a tratamento complementar com quimioterapia e radioterapia de acordo com o protocolo de Roger Stupp. Quatro anos após o diagnóstico inicial, ocorreu recidiva tumoral no seio sagital superior, sem evidência de recorrência em outro local. Na literatura, não encontramos nenhum caso semelhante publicado reforçando a raridade desta condição.
