摘　　要：目的 分析中枢神经细胞瘤的临床及磁共振成像（MRI）资料,探讨其MRI上的影像特点.方法 对9例病理证实的中枢神经细胞瘤MRI资料进行回顾性分析.结果 9例中枢神经细胞瘤均位于侧脑室孟氏孔区,矢状位侧脑室前、中1/3到2/3的区间,形态不规则有分叶,肿瘤信号混杂,增强后实性成分轻度到中等度强化,DWI上呈高、稍高信号.结论 中枢神经细胞瘤在MRI影像上部位、各序列信号变化有一定的特点,对于术前正确诊断中枢神经细胞瘤具有很高的价值.Objective To evaluate the characteristic appearance and diagnosis value of central neurocytoma on magnetic resonance imaging （MRI）.Methods MRI data of 9 patients with central neurocytoma confirmed surgically and pathologically were retrospectively reviewed.Results All the lesions located in the lateral ventricle septum pellucidum,adjacent to Monro hole,in the anterior 1/3 to 2/3 of the lateral ventricle.Most of them were irregularity,sublobe and sharpness of border.They presented as inhomogeneous intense signal on MRI,with slight to equal enhancement on enhancement.DWI could be high or slightly high signal.Conclusion Central neurocytoma has the characteristic appearances on MRI,being helpful to the diagnosis.
