摘　　要：目的:探讨神经节细胞胶质瘤(GG)的临床表现、影像学特征及其预后情况。方法:回顾性分析2019年2月至2021年7月手术病理诊断为GG的患儿。获取资料包括基本信息、影像学表现、手术及病理学数据及随访情况。结果:共纳人9例患儿,男女比例为2:1,年龄9个月~12岁6个月。发病部位为题叶4例、小脑2例、顶叶、枕叶及顶叶各1例。所有人组患儿均接受了手术治疗并存活至近期随访,但与次全切除患儿相比,全切除患儿的临床症状改善更明显。结论:GG的CT及MRI表现具有一定的特征,其增强扫描及弥散加权成像对GG的诊断具有重要的提示作用。全切除手术是GG的最佳治疗方法;然而相比于半球肿瘤,幕下GG即使全切除,其临床症状改善亦不显著。Purpose:To investigate the clinical manifestations,imaging features and prognosis of gangliogliomas(GG).Methods:A retrospective analysis was performed on the children with GG confirmed by surgical pathology results from February 2019 to July 2021.Data collected included demographics,imaging findings,surgical and pathological details,and follow-up information.Results:A total of 9 children aged 9 months to 12.5 years were included,with a male to female ratio of 2:1.The location of the tumor was temporal in four cases,cerebellar in two cases,and temporoparietal,occipital and parietal in one case,respectively.All enrolled children were treated surgically and survived until recent follow-up,but clinical improvement was more pronounced in children with total resection than those with subtotal resection.Conclusion:CT and MRI findings of GG have certain characteristics,and the contrast enhanced scan and diffusion weighted imaging play an important role in the diagnosis of GG.The total resection is the best treatment for GG;yet compared to hemispheric tumors,even total resection of infratentorial GG does not lead to remarkable improvement of clinical symptoms.
