É a variante histológica mais frequente do astrocitoma difuso. É predominantemente composto por astrócitos neoplásicos fibrilares. Atipia nuclear é um critério diagnóstico, mas atividade mitótica, necrose e proliferação microvascular estão ausentes. A ocorrência ocasional ou regional de células neoplásicas gemistocíticas é compatível com o diagnóstico de astrocitoma fibrilar. (OMS) | |||
