A 32-year-old woman in her first pregnancy, presented with acute-onset hemidystonia and hemianesthesia which occurred while vomiting, on a background of hyperemesis gravidarum. Magnetic resonance imaging of the brain demonstrated right basal ganglia, thalamic, and capsular intracerebral hemorrhage, and time-of-flight magnetic resonance angiography demonstrated an occluded right middle cerebral artery with associated lenticulostriate collateral vessels, consistent with Moyamoya phenomenon. This case highlights the importance of managing hyperemesis gravidarum in patients with Moyamoya phenomenon to avoid Valsalva forces which are associated with intracerebral hemorrhage.
一名32岁的初孕妇，在妊娠剧吐的背景下，出现呕吐时突发的急性半身肌张力障碍和半身感觉缺失。脑部磁共振成像显示右侧基底节、丘脑和脑室内囊出血，时间飞跃磁共振血管造影显示右侧大脑中动脉闭塞并伴有豆纹状侧支血管，符合烟雾病现象。该病例强调了对患有烟雾病现象的患者管理妊娠剧吐的重要性，以避免与脑出血相关的瓦氏动作。
