目的分析15例子癎患者头颅 MRI 的特点。方法对15例子癎患者进行回顾性分析,包括临床表现、头颅 MRI 特点及随访结果。结果患者的临床表现均有视物模糊、头痛、癫癎发作、高血压、蛋白尿和下肢水肿;影像学特点为13例仅对称性枕、顶叶白质信号异常,2例累及额叶、基底节区,1例还累及颞叶;病灶 DWI 上以等或低信号为主,ADC 图上病灶为高信号,2例 DWI 上出现高信号。15例均恢复良好,随访病灶均消失。结论子癎患者影像学改变以血管源性脑水肿为主,预后良好。
Objective To analyze the features of cranial MRI in 15 cases of children with subfamilies. Methods A retrospective analysis of 15 cases of subfamily patients, including clinical manifestations, head MRI features and follow-up results. Results The clinical manifestations of patients were blurred vision, headache, epilepsy, hypertension, proteinuria and lower extremity edema. Imaging features of 13 cases of only symmetrical pillow, parietal white matter signal abnormalities, 2 cases involving the frontal lobe, basal One case also involved the temporal lobe. The lesion was characterized by equal or low signal on DWI, high signal on ADC map, and high signal on 2 DWI. All 15 cases recovered well and all the follow-up lesions disappeared. Conclusion The imaging changes in children with vasogenic brain-derived brain edema, the prognosis is good.
