Moyamoya phenomenon occurs in response to an occlusive vasculopathy affecting the distal internal carotid artery and its proximal branches. The nature of the occlusive vasculopathy is unknown in most patients. We present a patient in whom 3T magnetic resonance imaging was used to examine the arterial wall at the site of occlusion in a patient with unilateral moyamoya phenomenon. Signal characteristics were consistent with atherosclerotic disease. 3T magnetic resonance imaging may be useful for distinguishing the underlying etiology of moyamoya phenomenon in some patients.
烟雾病样现象是由影响颈内动脉远端及其近端分支的闭塞性血管病变引起的。在大多数患者中,闭塞性血管病变的性质尚不清楚。我们报告了一名单侧烟雾病样现象患者,使用3T磁共振成像检查了闭塞部位的动脉壁。信号特征与动脉粥样硬化疾病一致。3T磁共振成像可能有助于区分某些患者烟雾病样现象的潜在病因。
