Astroblastoma is a rare glial tumor with uncertain histopathological origin and unpredictable clinical behavior. In this report, the authors present two cases of high grade intracerebral astroblastomas. Both tumors occurred in children as supratentorial, well-circumscribed, peripheral masses. The lesions differed radigraphically; one contained a huge cystic component and heterogeneously enhancing mural nodule while the other appeared as a prominently contrast-enhancing solid mass lesion. Both patients were treated with surgery and postoperative radiotherapy. They were followed-up long-term and no recurrence of the tumor was detected in either case. We also discussed the radiological and histological characteristics with prognostic features.
