In this retrospective study, 382 operated cases of meningiomas were reviewed. 32 cases (8.3%) were histopathologically classified as atypical meningioma. The anatomical locations and histological features in all the thirty-two cases were correlated with their recurrence rates and biological behaviour. The overall recurrence rate for atypical meningioma within two years was 28% as compared to 9.3% in benign meningiomas. It is being emphasized that an accurate histopathological interpretation of atypical meningioma is essential for predicting the recurrence, biological behavior as well as post-operative management modalities.
在这项回顾性研究中，对382例接受手术的脑膜瘤病例进行了回顾。32例（8.3%）在组织病理学上被分类为非典型脑膜瘤。将这32例病例的解剖位置和组织学特征与其复发率和生物学行为进行了关联分析。非典型脑膜瘤两年内的总体复发率为28%，而良性脑膜瘤为9.3%。需要强调的是，对非典型脑膜瘤进行准确的组织病理学解读对于预测复发、生物学行为以及术后管理方式至关重要。
