目的分析脑膜瘤术后复发的影像学特征,探讨脑膜瘤复发的相关因素。方法 120例脑膜瘤手术者,分为复发组24例及非复发组96例。分析两组CT或MRI影像学特征。结果复发组肿瘤位于凸面、颅底或幕下、窦旁或镰旁分别占54.17%(13/24)、16.67%(4/24)、29.16%(7/24),非复发组分别为45.83%(44/96)、36.46%(35/96)、17.71%(17/96),两组比较差异有统计学意义(P<0.05);复发组肿瘤为圆形、分叶形和蘑菇形脑膜瘤者分别占54.17%(13/24)、29.16%(7/24)、16.67%(4/24),非复发组则为68.75%(66/96)、21.87%(21/96)、9.38%(9/96),两组比较差异有统计学意义(P<0.05);复发组瘤内坏死灶25.00%(4/24),高于非复发组的6.25%(6/96)(P<0.05);复发组瘤内有钙化20.83%(5/24),高于非复发组的3.12%(3/96)(P<0.05);复发组发生骨质改变37.50%(9/24),高于非复发组的10.42%(10/96)(P<0.05);两组肿瘤大小、有无硬脑膜尾征、有无均一强化以及瘤周水肿程度比较,差异无统计学意义(P>0.05)。结论肿瘤部位、形状、有无瘤内坏死灶、钙化与有无骨质改变等影像学特征是脑膜瘤复发的相关因素,可作为脑膜瘤复发的预测指标。
Objective To analyze the imaging features of meningioma recurrence and explore the related factors of recurrent meningioma. Methods 120 cases of meningioma surgery were divided into 24 cases of recurrence group and 96 cases of non-recurrence group. Analysis of two sets of CT or MRI imaging features. Results The tumors in the recurrent group were located in the convex, skull base or infratentorial sinus, with 54.17% (13/24), 16.67% (4/24) and 29.16% (7/24) respectively, while those in the non-recurrent group were 45.83% (44/96), 36.46% (35/96) and 17.71% (17/96), respectively. The difference between the two groups was statistically significant (P <0.05). The tumors in the recurrent group were round, lobulated and mushroom- The tumors accounted for 54.17% (13/24), 29.16% (7/24) and 16.67% (4/24) respectively in the non-recurrence group and 68.75% (66/96), 21.87% (21/96) and 9.38 % (9/96), the difference between the two groups was statistically significant (P <0.05). The recurrence rate of intracranial necrosis was 25.00% (4/24) in the recurrence group, which was higher than that in the non-recurrence group (6.25%, P <0.05). The recurrence group had 20.83% (5/24) calcifications in the tumor group, which was higher than 3.12% (3/96) in the non-recurrence group (P <0.05) , Which was significantly higher than that of the non-recurrence group (10.42%, 10/96) (P <0.05). There was no significant difference in tumor size, presence or absence of dural tail sign, > 0.05). Conclusion The imaging features such as tumor location, shape, tumor-free necrosis, calcification and bone mass change are the related factors of meningioma recurrence, which can be used as a predictor of meningioma recurrence.
