摘　　要：目的 提高对中枢神经细胞瘤的影像学认识。方法 回顾性分析经病理证实的12例中枢神经细胞瘤患者的影像学表现,并结合相关文献进行总结研究。结果 12例患者（男8例,女4例,年龄22~40岁,平均32岁）肿瘤均位于侧脑室透明隔室间孔附近,形态均不规则,均有囊变及不均匀轻中度增强,6例CT显示有钙化,CT上肿瘤呈等或稍高密度,MRI上呈等T1或稍长T1、等T2或稍长T2信号。结论 中枢神经细胞有典型的发病部位及特征性的影像表现,结合临床综合分析,可提高其诊断准确率。Objective To improve the imaging recognition of the central neurocytoma. Methods The manifestations of 12 patients with central neurocytoma confirmed by pathological assessment were analyzed retrospectively and relevant literature were reviewed. Results The tumors of the 12 cases（8 males and 4 females, aged 22-40 years, mean 32 years）all originated from the foramen of monro close to the septum pellucidum. All tumors with irrugular shape showed cysticcomponents and enhancement. Six tumors showed calcification on CT. The tumors showed higher or equal density on CT scan, also hypointensity or equal signal in T1 and hyperintensity or equal signal in T2 on MRI scan. Conclusion CT and MRI imaging has some specificity that is helpful to the diagnosis of the central neurocytoma. The correct diagnosis may be obtained by analyzing CT and MRI findings, tumor position and clinical manifestations.
