[A case of HELLP syndrome resulting in eclampsia with non-aneurysmal subarachnoid hemorrhage].

It is known that hemorrhagic stroke at the perinatal period are caused by specifics conditions like eclampsia as well as by the existing abnormal vessels. We treated a case of HELLP syndrome resulting in eclampsia with non-aneurysmal, convexity subarachnoid hemorrhage. A 34-year-old female, who had been pointed out to have a high level of urinal protein at the 37th week, was seen in the emergency department because of severe headache, vomiting and respiratory discomfort. Her systolic blood pressure was over 190mmHg, and caesarean section was selected. On the way to the operating room, she had a generalized convulsion with loss of consciousness. The delivery was carried out. The CT immediately after the caesarean section revealed faint and localized subarachnoid hemorrhage in the bilateral convexity areas. Additionally, the FLAIR image of MRI demonstrated increased intensity in the bilateral cerebellar hemispheres, basal ganglion and subcortical area, suggesting vasogenic edema. The patient had a good clinical course and the abnormal signal of MRI also recovered by treatment with oral iron and zinc. Here, we report a speculation for the mechanism of this case and precautions against stroke in the perinatal period.
