Abstract
Three children were examined who had surgery to remove gangliocytomas in order to control seizures that were refractory to medical therapy. The CT characteristics of gangliocytomas are those of a hyperdense lesion that does not demonstrate contrast enhancement. The MR findings show a region of mixed signal intensity on T1-weighted and proton-density images, and decreased signal intensity on T2-weighted images. Little mass effect, if any, is seen with these lesions.
摘要
对三名接受手术切除神经节细胞瘤以控制药物治疗无效的癫痫发作的儿童进行了检查。神经节细胞瘤的CT特征为高密度病变，无强化表现。磁共振成像（MR）结果显示，在T1加权像和质子密度像上为混合信号强度区域，在T2加权像上信号强度降低。这些病变几乎没有占位效应（如果有的话）。
