MRI对伽玛刀治疗海绵窦海绵状血管瘤的疗效评估

摘要

目的：总结海绵窦海绵状血管瘤的MRI特点和伽玛刀的治疗经验，通过MRI随访评估伽玛刀治疗海绵窦海绵状血管瘤的疗效。方法收集9例经伽玛刀治疗的海绵窦海绵状血管瘤的MRI资料，对其治疗前后的MRI影像学征象进行对照分析。结果9例随访18~42个月，平均26个月。最近的MRI图像显示肿瘤缩小>90%的1例，缩小≥50%的7例，缩小>30%的1例。结论海绵窦海绵状血管瘤的MRI影像表现有较强特征性。伽玛刀治疗海绵窦海绵状血管瘤在随访期内的效果良好，可考虑作为该肿瘤的主要治疗方法。%Objective To summarize the MRI features and experience in Gamma knife treatment of cavernous sinus hemangioma and evaluate the curative effect through postoperative MRI follow-up. Methods The MRI data on nine patients receiving gamma knife treatment of cavernous sinus hemangioma were collected in order to analyze the MRI features and signs before and after the treatment. Resuits The follow-up lasted for 18-42 months for the nine patients,and the average follow-up time was 26 months. The latest MRI data showed that the tumor shrinkage exceeded 90% in one case,exceeded 50% in seven cases,and exceeded 30% in one case. Conciusion MRI findings of cavernous sinus hemangioma have strong characteristics. According to the follow-up,Gamma knife treatment of cavernous sinus hemangioma has favorable effect,so it can be considered as a main method in treatment of such tumors.
