Moyamoya disease is a rare, chronic cerebrovascular occlusive disease of unknown etiology. It is characterized by progressive stenosis of the arteries of the circle of Willis leading to ischemic strokes in young people and cerebral hemorrhage, which is more frequent in adults. Secondarily, an abnormal network of fine collateral vessels arises at the base of the brain. The term moyamoya refers to the angiographic appearance of the cerebral vasculature. We present such a disease in an 18-month-old Iranian girl with global developmental delay, which is a very rare presentation of moyamoya disease. She was diagnosed by magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA).
烟雾病是一种病因不明的罕见慢性脑血管闭塞性疾病。其特征是 Willis 环动脉进行性狭窄，导致年轻人缺血性中风，而脑出血在成年人中更为常见。其次，在脑底部会出现异常的细小侧支血管网络。“烟雾病”一词指的是脑血管造影的表现。我们报告了一名 18 个月大的伊朗女孩患有这种疾病，伴有全面发育迟缓，这是烟雾病非常罕见的表现形式。她通过磁共振成像（MRI）和磁共振血管造影（MRA）被确诊。
