子痫性脑病的CT诊断价值

The Value of CT in Diagnosing Eclampsia Brain Illness

目的探讨头部电子计算机断层扫描(CT)对子痫性脑病的诊断价值。方法回顾性分析5例经临床确诊为子痫性脑病患者的头部CT表现特征,分析其头颅CT表现。结果3例CT显示双侧顶叶及枕叶皮层或皮质下白质内基本对称性斑片状低密度,双侧额叶、双侧基底节、大脑镰旁白质内也可见,2例未见异常;经对症处理后复查示所有病变几乎完全吸收消失,临床症状也在2周～2个月内部分改善或痊愈。结论子痫性脑病影像学改变为血管性水肿所致,常累及双侧顶枕叶、小脑半球等后循环系统皮质或皮质下白质,CT能够显示后循环对称性低密度灶,正确认识子痫性脑病对早期诊断和治疗具有非常重要的意义。

Objective To investigate the value of CT to diagnose eclampsia cerebropathy. Methods Analyzed the CT features of 5 cases eclampsia cerebropathy after clinical diagnosis. Results 3 cases demonstrated symmetry patching low density in cortex or subcortical white matter bilateral apical lobe and occipital lobe. The same sign were seen in white matter bilateral frontal lobe, basal ganglia and para-cerebral falx. No abnormality seen in 2 cases. All the lesion were almost completely absorbed after symptomatic treatment and Clinical symptoms also partly improved or healed in 2 weeks to 2 months. Conclusion The imaging changes of Eclampsia cerebropathy were caused by angioedema. Cortex or subcortical white matter in the postal circulation system such as bilateral apical and occipital lobe and hemisphaerium cerebelli were often involved. CT could demonstrated the symmetry patching low density in postal circulation system. Correct understanding eclampsia brain illness has the very vital significance to the early diagnosis and the treatment.
