目的：分析缺血型烟雾病与出血型烟雾病磁共振(MR)影像特点的差别，提高预测烟雾病出血的概率。方法：回顾性分析64例烟雾病患者的临床及MR影像学资料。结果：64例烟雾病患者中，最大年龄49岁，最小年龄26岁，平均年龄38.2岁；其中缺血型烟雾病患者21例(占32.8%)，以额叶及顶叶分布为主；出血型烟雾病患者43例(占67.2%)，以背侧丘脑(共28例，占65.1%)、基底节区(共9例，占20.9%)、单纯脑室内(共4例，占9.3%)以及单纯蛛网膜下腔(共2例，占4.6%)分布为主。出现脑底烟雾状异常血管网、脉络膜前动脉及胼胝体背侧动脉增粗、大脑后动脉与皮质软脑膜血管增粗、眼动脉增粗、颈外动脉分支血管增粗在缺血型烟雾病及出血型烟雾病分别为15例共28侧支(占71.4%)和38例共62侧支(占88.4%)、12例共24侧支(占57.1%)和35例共45侧支(占81.4%)、8例共16侧支(占38.1%)和30例共58侧支(占69.8%)、5例共10侧支(占23.8%)和13例共24侧支(占30.2%)、7例共11侧支(33.3%)和27例共54侧支(62.8%)。结论：迂曲扩张的脉络膜动脉及颅底异常增生的血管网是烟雾病发生出血的主要原因。
目的：分析缺血型煙霧病與齣血型煙霧病磁共振(MR)影像特點的差彆，提高預測煙霧病齣血的概率。方法：迴顧性分析64例煙霧病患者的臨床及MR影像學資料。結果：64例煙霧病患者中，最大年齡49歲，最小年齡26歲，平均年齡38.2歲；其中缺血型煙霧病患者21例(佔32.8%)，以額葉及頂葉分佈為主；齣血型煙霧病患者43例(佔67.2%)，以揹側丘腦(共28例，佔65.1%)、基底節區(共9例，佔20.9%)、單純腦室內(共4例，佔9.3%)以及單純蛛網膜下腔(共2例，佔4.6%)分佈為主。齣現腦底煙霧狀異常血管網、脈絡膜前動脈及胼胝體揹側動脈增粗、大腦後動脈與皮質軟腦膜血管增粗、眼動脈增粗、頸外動脈分支血管增粗在缺血型煙霧病及齣血型煙霧病分彆為15例共28側支(佔71.4%)和38例共62側支(佔88.4%)、12例共24側支(佔57.1%)和35例共45側支(佔81.4%)、8例共16側支(佔38.1%)和30例共58側支(佔69.8%)、5例共10側支(佔23.8%)和13例共24側支(佔30.2%)、7例共11側支(33.3%)和27例共54側支(62.8%)。結論：迂麯擴張的脈絡膜動脈及顱底異常增生的血管網是煙霧病髮生齣血的主要原因。

Objective: To improve the accuracy of forecasting hemorrhagic moya-moya disease by analyzing the difference in MR imaging between ischemic moya-moya disease and hemorrhagic moya-moya disease. Methods: Retrospective analysis was conducted of clinical and MR imaging data of 64 patients with moya-moya disease between 2009 and 2014 years in Hospital 94 of PLA. Results: Among the 64 patients aged 26 to 49 (average age was 38.2), 21 cases (32.8%) were diagnosed with ischemic moya-moya diseases, while 16 cases (76.2%) diagnosed with hemorrhagic moya-moya diseases, ischemic lesions were distributed mainly in frontal and parietal area, while hemorrhagic lesions were mainly distributed in the dorsal thalamus (28 cases, 65.1%), in the basal ganglia (9 cases, 20.9%), in the simple intraventricular (4cases, 9.3%) and in pure subarachnoid (2 cases, 4.6%). In the ischemic-typed moyamoya disease and hemorrhagic-typed moyamoya disease, cerebral bottom dorsal smoke abnormal vascular network, anterior choroidal artery and callosal artery thickening of the posterior cerebral artery, cortical pial vascular thickening, thickening of vascular branches of ophthalmic artery and external carotid artery thickening were respectively occurred in 15 cases of 28 branch (71.4%) and 38 cases of 62 branches (88.4%), 12 cases with 24 branches (57.1%) and 35 cases with 45 branches (81.4%), 8 cases with 16 branches (38.1%) and 30 cases with 58 branches (69.8%), 5 cases with 10 branches (23.8%) and 13 cases of the 24 branch (30.2%), 7 cases with 11 side branches (33.3%) and 27 patients with 54 branch (62.8%). Conclusion:The tortuous and dilated choroid artery and abnormal hyperplasia vascular network in skull base are the main causes of bleeding in moya-moya diseases.
