摘要
目的 回顾分析 12例Moyamoya病的临床和影像学特征 ,探讨Moyamoya病的影像学诊断价值。方法 分析 12例Moyamoya病患者的临床资料及数字减影血管造影 (DSA)、磁共振血管造影(MRA)、磁共振成像 (MRI)和CT结果。结果 所有病例均表现有颈内动脉或其分支不同程度的狭窄或闭塞和颅底异常血管网 (MMD血管 ) ;其中病变呈双侧者 8例 ,单侧者 4例。 12例中头颅CT表现有梗塞灶者 4例 ,脑出血者 5例 ,其余 3例表现正常。结论 除DSA外 ,MRI和MRA是两种可以很好评价Moyamoya病的影像学方法。若儿童或青壮年发生脑血管病 ,反复出现脑梗死或出现脑室出血、脑叶出血或蛛网膜下腔出血 (SAH)则要考虑Moyamoya病的可能。
Objective To explore the diagnosis value of imaging presentations for Moyamoya disease by retrospectively analyzing clinical situations and imaging characteristics of 12 patients with Moyamoya disease. Methods Clinical data, as well as digital subtracted angiography(DSA), magnetic resonance angiography(MRA), magnetic resonance imaging(MRI) and CT findings of 12 patients with Moyamoya disease were studied. Results All patients showed stenosis or occlusion of the internal carotid arteries or their branches, and extensive abnormal basicranial vascular network, so -called moyamoya, was developed at the basal area of the brain; the lesion was bilateral in 8 cases and unilateral in 4 cases. On CT scan, cerebral infarction and hemorrhage were presented in 4 and 5 patients, respectively, while normal CT scan was seen in 3 patients. Conclusions It is suggested that there is a great possibility of suffering Moyamoya disease when occurring cerebral vascular disorder, recurrent cerebral infarction or ventricular hemorrhage, lobar hemorrhage or subarachnoid hemorrhage(SAH) in child or young people. In addition to DSA, MRI and MRA are the methods of choice in diagnosis of Moyamoya disease.
