semanticscholar(2019)
摘要
Oligodendrogliomas represent the 3 most common type of glial tumors, corresponding to between 4 and 15% of all gliomas of the central nervous system (CNS).1 Anaplastic oligodendrogliomas (AOs) (World Health Organization [WHO] grade III)2 correspond to 23% of all oligodendrogliomas.3 They correspond to a tumor with malignant histological characteristics, focal or diffuse, associated with a worse prognosis,1 in comparison to the oligodendrogliomas WHO grade II.2 Anaplastic oligodendrogliomas are associated with a 5and 10-year average survival rate of 63% and 33%, respectively.4 In the present case report, we describe the case of an AO with a pattern of tumor dissemination not described in the literature, into the superior sagittal sinus (SSS), with its consequent obliteration, in a patient with no evidence of tumor recurrence elsewhere.
