目的探讨妊高症并发皮层盲的影象学改变。方法就2例妊高症并发皮层患者的核磁(MRI)特点讨论其可能发病机制并进行相关文献复习。结果两例患者头部MRI示,枕叶皮质异常信号。结论妊高症并发皮层盲可能是脑后部可逆性脑病综合征的一个表现形式。 Objective To explore the imaging changes of blindness in pregnancy-induced hypertension complicated by cortex. Methods The MRI features of 2 patients with pregnancy-induced hypertension complicated with cortex were discussed and their possible pathogenesis were discussed and relevant literatures were reviewed. Results Two patients showed head MRI and abnormal occipital cortex signal. Conclusions Pregnancy-induced hypertension complicated with cortical blindness may be a manifestation of reversible encephalopathy syndrome in the posterior head.
