中枢神经细胞瘤(central neurocytoma,CNC)是位于孟氏孔区的一种少见脑肿瘤,根据其CT和MRI特征可作出神经影像诊断,像突触素一类的免疫标记物对CNC的组织学诊断很有帮助;再结合肿瘤部位及患者发病年龄可明显提高本病的诊断准确率.进一步提高认识和诊断水平有助于改善患者预后.,Central neurocytoma (CNC) is a rare brain tumor often located in the region of foramen of Monro. According to CT scanning, MRI diagnosis may carry on the neural imaging diagnosis. Many histological markers, such as synaptophysin, can be very useful for diagnosing CNC. It is possible to improve diagnostic accuracy of CNC combining with the tumor’s location and the patient’s age. Further studies may improve recognition and diagnostic level for better prognosis in CNC.
