偏瘫型偏头痛是复杂偏头痛的一种形式。在小儿,这种无痛性的偏头痛最初常表现为一过性偏瘫,其表现与一过性脑缺血发作难以鉴别。 烟雾病是一种少见的颅内段颈动脉和椎动脉病变,病因未明。烟雾病发生于儿童和青年并引起脑血管主干闭塞。最初表现为中风、抽搐或一过性脑缺血发作。脑血管造影常用来诊断该病,表现为毛细血管扩张形成栓塞的由于颈动脉远端的侧枝循环(日本人形象为吸烟者所喷出的烟雾),现在,磁共振成像(MRI)不仅能发现闭塞的异常血管,而且能识别基底节及瞄底部扩张的毛细血管网。 作者报告1例典型的偏瘫型偏头痛,经MRI诊断为烟雾病。 病例 患者是一女性,6岁,初诊主诉为发作
Hemiplegia Migraine is a form of complex migraine. In children, this painless migraine initially manifests itself as a transient hemiplegia, whose manifestation is indistinguishable from a transient ischemic attack. Moyamoya disease is a rare intracranial carotid artery and vertebral artery disease, the etiology is unknown. Moyamoya disease occurs in children and young adults and causes occlusions of the cerebrovascular trunk. Initially manifested as stroke, convulsions or transient ischemic attacks. Cerebral angiography is commonly used to diagnose the disease, manifested as capillary expansion dilatation due to the collateral circulation of the distal carotid artery (the Japanese image is smoke emitted by smokers), and now magnetic resonance imaging (MRI) can not only find Occlusion of abnormal blood vessels, but also to identify the basal ganglia and apex of the capillary network expansion. The authors report a typical case of hemiplegic migraine, diagnosed as moyamoya disease by MRI. Case patient is a female, 6 years old, the first complaint was an attack
