发布时间：2019-07-30 14:44
【摘要】：目的观察致癫痫性颞叶内侧肿瘤的MRI表现。方法回顾性分析28例经病理证实为致癫痫性颞叶内侧肿瘤患者的临床及MRI资料,对比观察不同病理类型病灶的位置、直径、信号等MRI表现。结果 28例中,神经元及混合性胶质-神经元肿瘤21例(21/28,75.00%),胶质瘤5例(5/28,17.86%),脑内海绵状血管瘤2例(2/28,7.14%)。23例肿瘤位于杏仁核-海马区,5例位于颞叶内侧其他区域。与胶质瘤相比,神经元及混合性胶质-神经元肿瘤直径多2cm(χ2=6.62,P=0.034),且瘤周水肿不明显(χ2=6.62,P=0.034)。28例中,18例发生囊变,9例发生钙化,不同病理类型肿瘤间囊变的发生率、囊变特点及钙化发生率差异均无统计学意义(P均0.05)。共15例合并FCD,神经元及混合性胶质-神经元肿瘤较其他病理类型更易并发FCD(χ2=5.791,P=0.029)。结论致癫痫性颞叶内侧肿瘤MRI表现具有一定的特征,病理类型以神经元及混合性胶质-神经元肿瘤最为多见。
