Abstract

Objective: The aim of this study was to investigate cranial magnetic resonance imaging (MRI) findings in different age groups and genders in pediatric epilepsy, to determine the percentages of etiologic factors, and to evaluate the association between MRI positivity and treatment resistance.

Methods: Cranial MRIs of 359 patients with epilepsy aged 1 month to 18 years were retrospectively evaluated. Etiologic factors as an underlying cause of epilepsy were classified as previous parenchymal damage, hippocampal sclerosis, malformations of cortical development, tumor, neurocutaneous syndrome, myelination disorder, vascular anomaly, metabolic/genetic/neurodegenerative diseases, encephalitis, and an uncategorized "other" group. Data were transferred to IBM SPSS Statistics 25.0 (SPSS Inc., Chicago, IL, USA), and descriptive statistics, correlation analyses, chi-square, and t-tests were performed.

Results: Among the patients included in the study, 141 (39.3%) had pathological findings on MRI related to the etiology. Previous parenchymal damage (39.7%) was the most common etiologic cause in all age groups. Regarding the relationship between drug resistance and MRI positivity, MRI positivity was observed in 72% of drug-resistant cases, while a complete response to therapy was found in 67.6% of MRI-negative cases.

Conclusion: MRI guides clinicians to determine the presence of an etiologic factor as the underlying cause of childhood epilepsy before treatment planning. MRI positivity is a remarkable indicator of response to antiseizure drug treatment and drug resistance.

头颅磁共振成像结果在小儿癫痫中的作用:单中心经验。
研究目的本研究旨在调查不同年龄组和性别的小儿癫痫患者的头颅磁共振成像(MRI)结果,确定致病因素的百分比,并评估 MRI 阳性与治疗耐药性之间的关联:方法:对359名1个月至18岁的癫痫患者的头颅磁共振成像进行回顾性评估。作为癫痫潜在病因的病因分为既往实质损害、海马硬化、皮质发育畸形、肿瘤、神经皮肤综合征、髓鞘化障碍、血管异常、代谢/遗传/神经退行性疾病、脑炎和未分类的 "其他 "组。数据被转入 IBM SPSS Statistics 25.0(SPSS 公司,芝加哥,伊利诺斯州,美国),并进行了描述性统计、相关性分析、卡方检验和 t 检验:在纳入研究的患者中,141 人(39.3%)在磁共振成像上发现了与病因相关的病理结果。在所有年龄组中,先前的实质损伤(39.7%)是最常见的病因。关于耐药性与磁共振成像阳性之间的关系,72%的耐药病例观察到磁共振成像阳性,而67.6%的磁共振成像阴性病例对治疗有完全反应:结论:磁共振成像可指导临床医生在制定治疗计划前确定儿童癫痫的潜在病因。磁共振成像阳性是抗癫痫药物治疗反应和耐药性的一个重要指标。
