Los oligodendrogliomas representan aproximadamente el 4–7% de todos los gliomas intracraneales primarios y acontecen más frecuentemente en pacientes en la 4ª–5ª década de la vida. Clásicamente se presentan en la mayor parte de los pacientes en forma de una larga historia clínica de epilepsia. Sin embargo, la mitad de ellos debutan con una variedad de síntomas, que incluyen déficits neurológicos focales y cefalea. La epilepsia como primer síntoma es una forma de identificar a los pacientes con buen pronóstico vital, mientras que el resto de los pacientes con las otras formas de presentación clínica, tienen un pronóstico y curso clínico más sombrío.
