摘要
目的 :研究脑膜瘤瘤周水肿的发生机制及相关因素。材料与方法 :对 33例经手术证实为脑膜瘤的瘤周水肿征象与病理进行对照研究。结果 :MRI所示的脑膜瘤瘤周水肿程度与肿瘤的良恶性程度有关联性 ,而与发生部位、大小无显著关联性。MRI上恶性脑膜瘤的瘤周水肿范围在一定程度上反映了肿瘤浸润的实际范围。结论 :根据脑膜瘤瘤周水肿的 MRI表现可推测肿瘤侵犯程度 。
Objective To study the occurence mechenism and correlative factors of peritumeral edema in meningioma. Materials and Methods The signs of peritumoral edema of 33 patients were made contrast study with their pathology. Results The degree of peritumoral edema on MRI scans was related to the malignant degree of meningioma, not the location and the size of tumor. The area of peritumor edema of malignant meningioma on MRI scan reflected the actual invading area of tumor in a certain extent. Conclusion According to the MRI manifestation of peritumor edema of meningioma, the invading extent of tumor may be predicted, which is helpful for surgical plan.
