儿童颅内动脉瘤较少见,约占病例总数的1％～2％。作者对3所医院20年内诊断的21例(男12例,女9例)共25个颅内动脉瘤的神经影像学等进行了研究。患者年龄从1个月到18岁,11例小于5岁。回顾所有的神经影像学资料发现,21例中19例经行CT,11例经MR检查,其中6例做了MRA。MRA检查范围含Willis环区,包括大脑中动脉近端和远端分支,大脑前动脉近端以及大脑后动脉的远端。这6例中 Children with intracranial aneurysms are rare, accounting for about 1% to 2% of the total number of cases. The authors studied the neurological imaging of 25 intracranial aneurysms in 20 hospitals (12 males and 9 females) diagnosed in 20 years. Patients ranged in age from 1 month to 18 years and 11 were younger than 5 years. Review of all neuroimaging data found that in 21 cases of 19 cases underwent CT, 11 cases by MR examination, of which 6 cases did MRA. The MRA range included the Willis annulus, which included the proximal and distal branches of the middle cerebral artery, the proximal cerebral artery, and the posterior cerebral artery. In these 6 cases
