目的：探讨中枢神经细胞瘤特征性影像学表现及其临床诊断价值。方法回顾性分析经临床病理证实的8例中枢神经细胞瘤患者的临床及影像资料，所有病例均行MR平扫及增强检查，其中3例同时行CT检查。结果8例均为青年人，所有肿瘤均位于侧脑室透明隔，并跨透明隔生长，邻近Monro孔，肿瘤均具有不规则形态；MR表现为T1WI上呈等、低信号，T2WI上呈不均匀稍高信号，特征性的表现为蜂窝状或丝瓜瓤样改变及“索条征”，增强后病灶轻至中度强化，囊变区无强化，肿瘤实质在CT平扫多呈等密度及稍高密度，多伴有散在钙化灶。结论 CT能清楚显示瘤内钙化，MR更能清晰显示瘤内丝瓜瓤样或蜂窝状改变，中枢神经细胞瘤的MR表现具有一定的特征性，对中枢神经细胞瘤的诊断具有重要价值。

Objective To investigate the clinical manifestation and diagnostic value of imaging examination in the central neurocytoma .Methods Retrospective analysis of 8 clinically and pathophysiologically proven central neurocytoma pa-tients imaging data and combined with other reports .All cases examined by plain and enhancement , both MR and CT scan were performed on 3 cases.Results 8 cases were young , all tumors were located in the lateral ventricle septum and growth across the septum, near Monro hole, tumors were of irregular shape;MR on T1WI showed iso-or low signal, T2WI showed on slightly uneven high signal , the performance characteristics of a honeycomb-like changes or loofahs and “streaks” sign, en-hanced lesions with mild to moderate enhancement , cystic no enhancement in CT scan tumor parenchyma mostly equal density and higher density , many accompanied by scattered calcification .Conclusion CT can clearly show intratumoral calcification , MR more clearly show the tumor loofahs or honeycomb-like changes in the MR appearance of central nervous system tumors have certain characteristics , for the diagnosis of central nervous system tumors has important value .
