| 摘 要： | 目的探讨颅内神经元和混合性神经元-神经胶质肿瘤的MRI表现及诊断价值。方法回顾分析16例患者均经手术病理证实为神经元和混合性神经元-神经胶质肿瘤的MRI资料。结果5例中枢神经细胞瘤有一定的MRI特征,3例诊断正确。8例神经节细胞胶质瘤中,7例位于或主要位于颞、枕叶,1例位于桥脑和延髓,表现为囊实性者5例,实性部分位于囊外的有3例,呈实性表现为局部脑回增厚者1例,囊变坏死明显者2例。3例小脑发育不良性节细胞瘤有特征性的条纹状或分层状表现。结论神经元和混合性神经元-神经胶质肿瘤是中枢神经系统少见的良性肿瘤,仔细分析MRI上某些特征性表现有助于术前诊断。

| Abstract: | Objective To study the MRI findings and diagnostic value of intracranial neuronal and mixed neuronal-glial tumors.Methods We retrospectively analyzed MRI findings of 16 patients with surgically and pathologically confirmed neuronal and mixed neuronal-glial tumors.Results MRI findings of central neurocytoma are specific in 5 cases.The ganglioglioma was found in the tempora and occipital lobe in 7 cases,in the brainstem in 1 case,cystic-solid tumor was observed in 5 cases with extramural nodule in 3 cases,obv... |
