目的探讨边缘系统胶质瘤的临床表现、影像学特点、病理特征以及显微手术治疗。方法回顾性分析28例经手术和病理确诊的边缘系统胶质瘤患者的临床资料。结果24例边缘系统胶质瘤患者以癫痫发作为其临床特点;CT扫描19例呈低密度,9例呈混杂密度;MRI扫描,T1低信号,T2高信号,多无强化;肿瘤全切19例,次全切6例,部分切除3例;术后5例患者出现暂时性运动性失语,6例出现对侧肢体偏瘫,其余恢复良好;随访6个月至5年,生存23例。结论应用高分辨CT或MRI可显示边缘系统胶质瘤与其周围结构的关系,可通过显微手术切除肿瘤,并可取得良好效果。
Objective To investigate the clinical manifestations, imaging features, pathological features and microsurgical treatment of limbic gliomas. Methods The clinical data of 28 patients with marginal system glioma confirmed by surgery and pathology were retrospectively analyzed. Results Twenty-four patients with limbic gliomas underwent epilepsy as their clinical features. Nineteen patients underwent CT scan with low density and nine patients with mixed densities. MRI scans showed low T1, high T2, and no enhancement. Tumor resection 19 Six cases were subtotectically resected and three cases were partially resected. Temporary exercise aphasia occurred in 5 cases and contralateral limb hemiplegia was found in 6 cases. The rest recovered well. The follow-up ranged from 6 months to 5 years and survived in 23 cases. Conclusion The application of high-resolution CT or MRI can show the relationship between the marginal glioma and its surrounding structures. The tumors can be removed by microsurgery and good results can be achieved.
