| 目的 对儿童颞叶癫痫进行前瞻性MRI研究分析,探讨儿童颞叶癫痫的MRI表现特征。方法 对127例临床和脑电图检查诊断为颞叶癫痫的儿童进行MRI多序列成像,分析研究颞叶的形态结构、信号并判断海马有无萎缩性改变。结果 127例颞叶癫痫患儿中,9例(7.1%)海马有萎缩性改变,且在T2加权成像和液体率减恢复(FLAIR)成像上呈高信号。9例中,6例伴有海马受累同侧颞叶信号异常;3例伴有同侧颞叶皮层结构不良;1例伴有同侧颞叶萎缩。结论 颞叶中内侧硬化是儿童颞叶癫痫的一个相对少见原因,受累侧海马MRI表现为萎缩和信号异常,同时常伴海马外颞叶结构受累。 |

| Objective [WTBZ]To prospectively study the temporal lobe epilepsy (TLE) in children and explore the MRI features of children's TLE.[WTHZ]Methods [WTBZ]One hundred and twenty seven children of TLE diagnosed with clinics and EEG underwent multi-series MRI examinations. The morphology and signal intensity and whether having hippocampal atrophic change of the temporal lobes were analyzed.[WTHZ] Results [WTBZ]Of 127 patients, 9 (7.1%) cases had hippocampal atrophy and showed hyperintense on T2-weighted and fluid-attenuated inversion recovery imaging (FLAIR). Of the nine patients, six showed abnormal signals, three associated with cortical dysplasia in involved temporal lobes and one associated with ipsilateral temporal lobe atrophy.[WTHZ] Conclusion Hippocampal sclerosis (HS) was a relatively less common causes in children's TLE. Hippocampal atrophic change and hyperintense on T2-weighted and FLAIR imaging were characteristic MR features of HS, but the ipsilateral temporal lobe of the involved hippocampus showed more abnormal than adult HS. |
