目的 探讨脑内神经节胶质瘤的影像学诊断价值 ,以提高对本瘤的认识。方法 回顾性分析 4例经手术及病理证实的神经节胶质瘤的临床和影像学资料。其中 2男 2女 ,年龄 14～ 47岁 ,平均约 2 7岁。结果 病变位于右颞叶 2例 ,左额叶和小脑蚓部各 1例 ,3例为囊实性 ,1例为完全囊性 ,边缘水肿不明显。MRIT1WI上囊性部分为低信号 ,壁瘤结节部分呈稍低信号 ,3例Gd -DT PA增强扫描显示病灶呈边缘性和壁瘤结节强化 ,T2 WI上病灶均为高信号。结论 神经节胶质瘤是中枢神经系统罕见的肿瘤 ,缺乏特异性影像学表现 ,如果发病年龄较小 ,病变位于大脑颞叶和小脑 ,病灶多呈囊性或囊实性 ,呈环形和壁瘤结节性强化 ,应考虑本病的可能性
Objective To investigate the diagnostic value of brain ganglion glioma in order to improve the understanding of this tumor. Methods The clinical and imaging data of 4 ganglion gliomas confirmed by surgery and pathology were retrospectively analyzed. Of which 2 men and 2 women, aged 14 to 47 years old, an average of about 27 years old. Results The lesions were located in the right temporal lobe in 2 cases, the left frontal lobe and cerebellar vermis in 1 case, 3 cases of cystic solidity, 1 case of complete cystic, marginal edema was not obvious. MRIT1WI cystic part of the low signal, the tumor nodules was slightly lower signal, 3 cases of enhanced Gd-DT PA scan showed margins and enhancement of aneurysm nodules, T2 WI lesions were high signal. Conclusion Gliomas of the ganglion are rare tumors of the central nervous system and lack specific imaging findings. If the age of onset is small, the lesions are located in the temporal lobe and cerebellum of the brain. Most of the lesions are cystic or cystic, Nodular enhancement, should consider the possibility of this disease
