Astroblastoma is a rarely diagnosed primary brain neoplasm whose histogenesis has been clarified recently. It occurs in children and young adults and presents as a well circumscribed, contrast-enhancing lesion in the cerebral hemisphere. We present a case of 20-year-old woman with an astroblastoma in the left temporal convexity that was treated with total tumor resection alone. We thought the mass was extra-axial neoplasm based on radiological findings of computed tomography and magnetic resonance imaging initially, but later, we obtained angiographic findings suggesting an intra-axial neoplasm. The patient is doing well even two years after surgery. The characteristic radiological and histopathological features of this case are described with a literature review. An astroblastoma should be included in the differential diagnosis of a superficially located tumor presenting with the findings of an extra-axial mass, especially in a young patient.
成星形细胞瘤是一种诊断罕见的原发性脑肿瘤，其组织发生最近已被阐明。它发生于儿童和年轻人，表现为大脑半球边界清晰、有强化的病灶。我们报告一例20岁女性，其左颞叶凸面患有成星形细胞瘤，仅接受了肿瘤全切治疗。最初，基于计算机断层扫描和磁共振成像的影像学表现，我们认为该肿块是轴外肿瘤，但后来血管造影结果提示为轴内肿瘤。即使在术后两年，患者情况仍良好。本文结合文献复习描述了该病例的特征性影像学和组织病理学表现。对于表现为轴外肿块的浅表性肿瘤，尤其是年轻患者，成星形细胞瘤应纳入鉴别诊断。
