Moyamoya syndrome is associated with other underlying conditions such as sickle cell disease, neurofibromatosis or collagen disorders. The posterior circulation is commonly involved although it is true that the terminal internal carotid arteries are more commonly affected. The most common presentation is that of watershed infarction either in the anterior, posterior or parasagittal distributions. Conventional arterial territory infarcts are relatively uncommon due to the diffuse vasculopathy.\u003c/p\u003e","id":2799,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/2799","nextQuestionPath":null,"relatedArticles":[{"id":1693,"title":"Moyamoya disease","link":"/articles/moyamoya-disease-1?lang=us"}],"alsoUsedIn":[{"id":1724,"kind":"Course","title":"2023 Virtual Conference Private Use - page 1724","link":"https://radiopaedia.org/courses/2023-virtual-conference-private-use/pages/1724"},{"id":365,"kind":"LiveSchedule","title":"365","link":"https://radiopaedia.org/admin/live_schedules/365"},{"id":278,"kind":"LiveSchedule","title":"278","link":"https://radiopaedia.org/admin/live_schedules/278"},{"id":1483,"kind":"Course","title":"2023 Virtual Conference Private Use - page 1483","link":"https://radiopaedia.org/courses/2023-virtual-conference-private-use/pages/1483"},{"id":1483,"kind":"Course","title":"Paediatric Lectures - page 1483","link":"https://radiopaedia.org/courses/paediatric-lectures/pages/1483"}],"stem":"\u003cp\u003eWhich of the following statements is true of Moyamoya vasculopathy?\u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/2799"}],"attemptsPercentages":[{"alternativeId":"13658","percentage":40},{"alternativeId":"13660","percentage":3},{"alternativeId":"13659","percentage":15},{"alternativeId":"13661","percentage":9},{"alternativeId":"13657","percentage":32}],"promptToLogin":false,"questionManager":false,"articleId":"suzuki-staging-system-for-moyamoya-disease"}
