影响脑膜瘤术后复发的影像学特征的研究进展

Research progress of radiography features impacting postoperative relapse of meningioma

脑膜瘤是常见的颅内肿瘤,大多数脑膜瘤为良性,生长缓慢,预后良好。然而即使全切除后,脑膜瘤仍有较高的复发率。随着影像学技术的发展,人们发现脑膜瘤的某些术前影像学特征即可在一定程度上预测其术后复发率。是否有重要结构受累、肿瘤的形状、瘤周水肿、脑膜尾征、磁共振成像特点等均是影响脑膜瘤术后复发的预测因素。本文将与脑膜瘤术后复发相关的术前影像学特征进行综述。

Meningiomas are common intracranial tumors,and most of them are benign,grow slowly and have good prognoses.However,even after total resection,meningiomas still have high relapse rates.With the development of radiography technology,it has been found that some preoperative radiography features of meningioma can predict the postoperative relapse rates to a certain extent.Whether there are important structures involved,tumor shape,peritumoral edema,meningeal tail sign,and magnetic resonance imaging features are all the predictors of postoperative relapse of meningioma.The preoperative radiography features related to postoperative relapse of meningioma were reviewed as follows in this article.
