脑胶质瘤是最常见的颅内肿瘤,局部侵袭是脑胶质瘤的一个显著特征,典型的肿瘤有一个中央坏死灶,周围致密肿瘤细胞区,外绕被肿瘤细胞侵袭的脑组织。手术仍是目前临床上最主要和最基本的治疗方法,在保存正常脑组织的前提下尽可能的切除肿瘤一直是脑胶质瘤手术治疗中应遵循的基本原则。术中显微镜下,这些肿瘤似乎边界清楚,但组织学上却发现有循血管和有髓纤维路径局部侵袭。由于胶质瘤 Glioma is the most common intracranial tumor. Localized invasion is a prominent feature of gliomas. The typical tumor has a central necrosis, a dense tumor cell surrounding and a brain tissue that is invaded by tumor cells. Surgery is still the most important and the most basic treatment in clinic at present. It is the basic principle that should be followed in the surgical treatment of glioma that resection of the tumor is possible under the premise of preserving normal brain tissue. Under the intraoperative microscope, these tumors appear to have clear boundaries, but histologically they have been found to have localized invasion of the vascular and myelinated fibers. Because of glioma
