烟雾病MRI影像与临床分析

MRI and climcal analysis of Moyamoya disease

目的探讨烟雾病的MRI诊断特征。方法 分析7例烟雾病患者的常规MRI和TOFMRA征象与临床表现。结果 1.一侧丘脑出血3例,多发小灶性梗塞2例,脑白质缺血和出血性梗塞各1例;基底节区迂曲血管影6例,环池、鞍上池迂曲血管影7例。2.大脑中动脉M1段狭窄的4例,全段不显影的3例;大脑前动脉A1段狭窄的3例,全段不显影的4例;大脑后动脉主干狭窄及不显影的各3例,一侧主干狭窄的1例。结论 诊断烟雾病应结合脑池与基底节区的常规MRI和TOFMRA表现。

Objective To probe the MRI diagnostic characteristic of Moyamoya disease. Methods The conventional MRI and TOFMRA of the brain and the clinical manifestation were analyzed in seven patients with Moyamoya disease. Results 1. Thalmus hemorrhage was noted in 3 patients, multiple focular infarction in 2 cases, ischemia and hemorrhagic infarction was displayed in 1 patient, respectively. Tortuous blood vessels in the basic ganglion were demonstrated in 6 patients and those in both suprasellar and ambient cisterns were noted in 7 patients. 2. Bilateral narrowed M1 segment and un - demonstrated whole course of the middle cerebral artery was found in 4 cases and 3 cases, respectively. Bilateral narrowed A1 segment and un - demonstrated whole course of the anterior cerebral artery was found in 3 cases and 4 cases, respectively. Bilateral narrowed and un - demonstrated trunk of the posterior cerebral artery was noted in 3 cases, respectively, and unilateral narrowed trunk noted in 1 case. Con-clusion The diagnosis of Moyamoya disease should be based upon the combination of the manifestations of both conventional MRI of the cisterns, basic gangfion and TOFMRA.
