摘　　要：目的提高对颅脑静脉性血管瘤的再认识。方法与资料自2011年1月～2013#-10B所遇到6例颅脑静脉性血管瘤；磁共振扫描仪为GE Signa HDe 1．5T及安科SuperVan1．5T。常规扫描T1WI、T2WI、FLAIR、DWI，可疑病例加扫GRET2＊、SWI、MRA、MRV。结果病灶多位于额叶白质内，同侧侧脑室旁，T1WI为等、高或低信号，T2WI为高或低信号，SWI、GRET2。序列为点、条状低信号，MRA、MRV均未见明显异常，增强扫描可见“水母头”样强化。结论MRI是诊断静脉性血管瘤的有效方法，磁共振增强扫描“水母头”是特征性表现。Objective To improve the understanding of cerebral venous angioma. Methods and materials A total of 6 cases of cerebral venous angioma from January 2011 to October 2013 were concluded, the conventional scanning sequences were T1W, T2WI, FLAIR and DWI, GRE T2＊ scanning, SWI, MRA and MRV scanning were added in suspected cases with the MRI scanner of the GE Signa HDe 1.5T or the SuperVanl.5T. Results The lesions were located in the frontal lobe or in the ipsilateral lateral ventricle, showed high or low signal on T1WI, high or low signal on T2WI. The lesion performed as points or parallel low signal on SWI, GRE T2＊ sequence, and showed no obvious abnormalities on MRA or MRV. ＂Jellyfish head＂ like enhancement could be seen in enhancement scanning. Conclusion MRI is valuable in the diagnosis of venous hemangioma and ＂jeliyfish head＂ is the characteristic features on enhanced MRI.
