目的探讨高海拔地区妊高征子痫患者颅脑CT和MRI表现。方法回顾性分析高原地区28例妊高征子痫患者的临床和影像学资料。结果28例子痫患者中,脑部CT正常者3例;CT和MRI示脑水肿者18例,其中轻度脑水肿2例、局灶性脑水肿11例和弥漫性脑水肿5例;脑出血6例,表现为额、颞、枕顶叶出血者4例,蛛网膜下腔出血2例;矢状窦静脉血栓形成1例。MRI较CT更能清晰显示脑内水肿的程度及有无出血情况。结论CT和MRI检查对妊高征子痫患者脑部损害的部位和程度以及预后和临床治疗有重要的价值。 Objective To investigate the CT and MRI features of brain in patients with PIH at high altitude. Methods The clinical and imaging data of 28 patients with PIH were analyzed retrospectively. Results Of the 28 patients with eclampsia, 3 were normal brain CT, 18 were cerebral edema by CT and MRI, 2 were mild cerebral edema, 11 were focal cerebral edema and 5 were diffuse cerebral edema. Cerebral hemorrhage 6 cases showed forehead, temporal, occipital parietal hemorrhage in 4 cases, 2 cases of subarachnoid hemorrhage; sagittal sinus venous thrombosis in 1 case. MRI can clearly show the degree of intracerebral edema and the presence or absence of bleeding more clearly than CT. Conclusion CT and MRI examination of PIH patients with brain damage in the site and extent of prognosis and clinical treatment of great value.
