摘要
目的：研究ＳｉｍｐｓｏｎⅠ、Ⅱ级切除突面脑膜瘤术后复发的原因。方法：通过突面脑膜瘤全切术后复发患者的临床、增强ＭＲＩ、头颅ＣＴ及病理结果和手术切除范围等因素来分析术后肿瘤复发的原因。结果：脑膜瘤细胞沿硬脑膜浸润的范围比ＣＴ和增强ＭＲＩ显示的范围大。结论：手术切除硬脑膜范围不够是术后肿瘤复发的根本原因。在ＳｉｍｐｓｏｎⅠ、Ⅱ级切除的基础上，切除增强ＭＲＩ显示的硬脑膜“尾”征＋０．３ｃｍ、或不具备硬脑膜“尾”征的肿瘤累及硬脑膜区域以外０．５ｃｍ的硬脑膜和静脉窦。
Purpose:To investigate the pathogenesis of meningioma recurrence after grade I、Ⅱ Simpson resection.Methods:The clinical manifestations,gadolinumenhanced MRI,CT scan, pathologic examination and resection area were considered to analyse the pathogenesis of the recurrence of brain convexity meningioma after total resection.Results:The infiltrated area of meningiothelioma cell along dura was larger than that showed by CT scan and gadolinumenhanced MRI.Conclusion:The insufficient resected area of dura is the essential reason for meningioma recurrence. On the basis of grade I、Ⅱ Sinpson resection,the tumour recurrence can be effectively prevented only by resecting the dural “tail' showed by gadolinumenhanced MRI plus 0.3 cm or by resecting the dura and vein 0.5 cm away from infiltrated area without the dural “tail”.
