目的探讨脑静脉血管瘤的ＭＲ表现并评价其诊断价值。方法本组搜集１５例ＭＲ诊断为脑表脉血管瘤的病例，对其ＭＲ表现进行分析（其中６例行ＤＳＡ检查）。结果１５例均能在ＭＲ上显示典型的“水母头”状形态，而增强扫描显示的更清楚，且能显示其静脉引流方向，同时ＭＲ能显示其它合并症。１５例中位于幕上１０例，小脑半球４例，１例多发，分别位于小脑及丘脑。结论ＭＲＩ是确诊脑静脉血管瘤的首选检查方法，并有助于指导临床治疗。
Objective To investigate the MR findings of cerebral venous hemangioma and evaluate its diagnostic value. Methods The group collected 15 cases of MR diagnosis of cerebrovascular hemangioma cases, their MR performance analysis (including 6 DSA). Results All of the 15 cases showed typical “jellyfish head” morphology on MR, and the enhanced scan showed more clearly and could show the direction of venous drainage. At the same time, MR could show other complications. In 15 cases, there were 10 cases in the supratentorial space, 4 cases in the cerebellum hemisphere and 1 case in the cerebellum and thalamus. Conclusion MRI is the first choice for the diagnosis of cerebral venous hemangioma and is helpful to guide the clinical treatment.
