颞叶癫痫(Temporal lobe epilepsy,TLE)是最常见的局灶性癫痫,目前手术已成为常用的治疗手段,术后疗效已得到证实[1]。颞叶癫痫最常见的病理改变是海马硬化,高分辨率MRI对其具有高度灵敏性(97%)及特异性(83%),是定位癫痫灶的最基本的影像学手段,而在MRI影像上发现海马硬化(HS)、皮质发育不良(MCD)、肿瘤及血管畸形等影像学改变已作为预测良好预后的独立因素[2]。但部分颞叶癫痫患者表现为MRI无异常改变,我们称之为MRI阴性颞叶癫痫(MRI-negative TLE)、正常MRI颞叶癫痫
Temporal lobe epilepsy (TLE) is the most common focal epilepsy. At present, surgery has become a commonly used treatment and postoperative efficacy has been confirmed [1]. The most common pathological changes of temporal lobe epilepsy are hippocampal sclerosis. High-resolution MRI is highly sensitive (97%) and specificity (83%), which is the most basic imaging method for locating epileptic foci. In MRI images Imaging changes such as hippocampal sclerosis (HS), cortical dysplasia (MCD), tumors, and vascular malformations have been identified as independent predictors of good prognosis [2]. However, some patients with temporal lobe epilepsy showed abnormal changes in MRI, we call it MRI-negative temporal lobe epilepsy (MRI-negative TLE), normal MRI temporal lobe epilepsy
