神经元和混合性神经胶质肿瘤的影像学表现
Imaging of intracranial neuronal and mixed neuronal-glial tumours
【摘要】 目的 探讨颅内神经元和混合性神经胶质肿瘤临床、影像与病理学特征。方法 对 14例经手术、病理证实的颅内神经元和混合性神经胶质肿瘤资料进行回顾性分析 ,其中男 7例 ,女 7例 ,年龄 6~ 5 6岁 ,平均 33 8岁。结果 神经节神经胶质瘤 8例 ,肿瘤位于额叶 4例 ,颞叶 1例 ,额颞叶 2例 ,桥脑 1例。CT为低等密度 ,MRT1WI为低等信号 ,T2 WI为高信号。中枢神经细胞瘤 2例 ,位于幕上脑室。促纤维增生性节细胞胶质瘤 4例 ,均为囊性 ,MRT1WI为低信号 ,T2 WI为高信号。结论 神经元和混合性神经胶质肿瘤具有一定的影像学特点 ,结合病史多数情况下可做出术前倾向性诊断。
【Abstract】 Objective To investigate the characteristic clinical, imaging, and pathologic findings of intracranial neuronal and mixed neuronal-glial tumours. Methods The imaging findings of surgery and pathobiology proved intracranial neuronal and mixed neuronal-glial tumours in 14 cases (7 male and 7 female, ranging in age from 6-56 years; mean age 33.8 years) were retrospectively analyzed. Results Eight gangliogliomas were located in the frontal lobe (4 cases), temporal lobe (1 case),fronto- temporal lobe(2 cases), and pons (1 case). They appeared as iso-or low density on CT, iso-or low signal intensity on T 1WI, and high signal intensity on T 2WI on MR imaging. Two central neurocytomas were located in the supratentorial ventricles. Four desmoplastic gangliogliomas were seen as cystic masses, appearing as low signal intensity on T 1WI and high signal intensity on T 2WI Conclusion Intracranial neuronal and mixed neuronal-glial tumours had imaging characteristics. Combined with clinical history, it was possible to make a tendency preoperative diagnosis using CT or MR.
