It is usually localized to the cerebral hemisphere. Computed tomography and magnetic resonance imaging show a well-demarcated, contrast-enhancing mass with a cystic area. Characteristic histological findings are perivascular pseudorosette formation and frequent vascular hyalinization. The presented case is a 3.7-month-old female patient diagnosed with high-grade astroblastoma.Case Presentation We report the case of a 3.7-year-old female patient admitted to the neurosurgery clinic with strabismus for 25 days. Magnetic resonance imaging revealed a contrast-enhancing mass that contained cystic and necrotic areas. The tumor mass has been totally resected and histological examination combined with immunohistochemical study confirmed the diagnosis of high-grade astroblastoma.eninfo:eu-repo/semantics/openAccessastroblastomabrainneuroepithelialArticle10.1055/s-0042-1744245WOS:000937906800005Q4
