Variante rara de astrocitoma difuso. É predominantemente composto por astrócitos neoplásicos apresentando um pequeno corpo celular com poucos processos flácidos e baixo conteúdo de filamentos gliais e escassa expressão de GFAP. Esta lesão não está bem definida e é considerada por alguns autores como uma característica histopatológica ocasional, ao invés de uma variante reproduzível identificável. Quando ocorre em crianças, essa neoplasia pode ser difícil de separar do astrocitoma juvenil pilocítico. (Adaptado da OMS) | |||
