Neoplasia glial rara mais comumente encontrada em adultos jovens. É caracterizada por células tumorais com características sugestivas de origem astrocítica (positivas para GFAP), dispostas perivascularmente. As células têm prolongamentos espessos e sem redução gradual que se propagam radialmente em direção a vaso sanguíneo central. O comportamento biológico dos astroblastomas é variável, portanto não há uma gradação do tumor pela OMS, ainda. | |||
