| 摘 要： | 目的 探讨中枢神经细胞瘤(CNC)的常规磁共振成像(MRI)和氢质子磁共振波谱(1H MRS)的表现特征和诊断价值.方法 回顾性分析5例经手术病理证实的CNC进行常规MRI检查,其中4例加做多体素1H MRS,并分析其MRI及1H MRS表现.结果 5例CNC患者肿瘤特征性位于侧脑室,邻近Monra孔并累及透明隔.在T1加权成像4例呈等低不均匀信号,1例呈等高不均匀信号;T2加权成像呈等高不均匀信号;增强后肿瘤呈中度及明显不均匀强化.4例1H MRS均表现为胆碱峰明显增高,N-乙酰门冬氨酸(NAA)峰下降,胆碱/肌苷比值升高,NAA/肌苷比值降低.结论 20~40岁的患者发生于侧脑室透明隔处邻近Monra孔的肿瘤,结合其MRI及1H MRS表现特征应考虑到CNC诊断.

| Abstract: | Objective To investigate the manifestation features and diagnostic values of magnetic resonance imaging(MRI)and proton magnetic resonance spectroscopy(~1H-MRS)in central neu- rocytoma(CNC).Methods 5 cases of CNC confirmed pathologically were examined with routine MRI,out of them,4 cases were examined with multivoxel MR proton spectroscopy.Results All of CNC masses in our study were typically located in the ventricles near the foramen of Monra with a characteristic attachment to the septum pellucidum.4 cases... |
