Gliosarcoma is a brain neoplasm that is being recognized with increasing frequency. We discuss the radiographic findings in 14 pathologically proven cases. At angiography in nine cases, four showed mixed dural and pial vascular supply to the lesion. Early cortical venous drainage, irregular tumor vessels, and a prominent vascular stain with well-defined tumor margins were seen in the majority of cases. CT showed an irregular enhancing rim surrounding a necrotic center in 14 cases. Most lesions were peripherally located and invaded dura.
胶质肉瘤是一种越来越常被识别出的脑肿瘤。我们讨论了14例经病理证实病例的影像学表现。9例进行血管造影检查的病例中，4例显示病变有硬脑膜和软脑膜混合供血。大多数病例可见早期皮质静脉引流、不规则肿瘤血管以及边界清晰的明显肿瘤染色。CT显示14例病例中坏死中心周围有不规则强化边缘。大多数病变位于周边并侵犯硬脑膜。
