脑发育性静脉血管异常的影像学探讨(附2例报告)

Cerebral developmental venous anomalies (two cases report and review)

目的探讨脑发育性静脉畸形(DVAs)的影像特征。方法对2例MRI误诊,后经血管造影确诊的DVAs患者的影像学资料作回顾性分析。结果2例患者一例为典型性DVA、一例为非典型性DVA。结论血管造影仍是DVAs诊断的“金标准”。

Objective To investigate the radiological characteristics of developmental venous anomalies(DVAs) of brain. Methods The radiological document of two cases of DVAs which misdiagnosed by MRI, and diagnosed by digital substraction angiography were evaluated retrospectively. Results In two patiens,one was typical and another was atypical in digital subtraction cerebral angiography. Conclusion Angiography is still the “gold standard ”for DVAs diagnosis.
