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 moyamoya 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.
