Herniação cerebelar transtentorial ascendente refere-se a efeito de massa na fossa posterior deslocando o mesencéfalo para cima. Isso pode produzir sintomas difusos de hidrocefalia obstrutiva se o aqueduto cerebral ou quarto ventrículo forem ocluídos, ou hemianopsia homônima se a artéria cerebral posterior (PCA) impactar na borda tentorial. | |||
