影响脑膜瘤术后复发的影像相关因素分析

Imaging correlated factors on postoperative recurrence of meningiomas

目的:探讨脑膜瘤切除术后复发的影像相关因素。方法:对20例复发性和98例非复发性脑膜瘤的临床资料、CT、MRI影像进行了对比分析。结果:蕈形及结节形者肿瘤复发率显著高于圆形者(P<0.01);中度和重度水肿组复发率显著高于无水肿和轻度水肿组(P<0.05);无钙化肿瘤复发率显著高于有钙化肿瘤(P<0.01);骨质溶解肿瘤复发率显著高于骨质增生肿瘤(P<0.01);有肿瘤内坏死复发率显著高于无肿瘤内坏死肿瘤(P<0.01);非均一强化肿瘤复发率显著高于有均一强化肿瘤(P<0.01)。结论:CT、MRI表现为蕈形及结节形者、严重瘤周水肿、无钙化、周围骨质溶解、肿瘤内坏死及肿瘤非均一强化者具有较高的术后复发率。复发率的高低顺序依次为周围骨质溶解、肿瘤内坏死、蕈形及结节形者、肿瘤非均一强化、无钙化、严重瘤周水肿。其中有周围骨质溶解者复发率远远高于其它(P<0.01)。

Objective：To study the imaging correlated factors on postoperative recurrence of meningiomas.Methods：The clinical,CT,MRI data of 20 recurrence cases after operation and 98 non-recurrence cases after operation were studied.Results：The recurrence of surname shape and nodiform meningiomas was higher than round meningiomas,（P〈 0.01）;The recurrence of midrange and severe edema around meningiomas was higher than no-edema or light edema around meningiomas（P〈 0.05）;The recurrence of no calcification meningiomas was higher than calcification meningiomas（P〈 0.01）;The recurrence of acro-osteolysisi was higher than hyperostosis meningiomas（P〈 0.01）;The recurrence of intratumorally necrosis meningiomas was higher than no intratumorally necrosis meningiomas（P〈 0.01）;The recurrence of non uniform enrichment meningiomas was higher than uniform enrichment meningiomas（P〈 0.01）.Conclusion：The apperence of CT,MRI with surname shape and nodiform,severe edema around meningiomas,no calcification,intratumorally necrosis,non uniform enrichment meningiomas,acro-osteolysisi have higher recurrence.The recurrence sequence is acro-osteolysis,intratumorally necrosis,surname shape and nodiform,non uniform enrichment,no calcification,severe edema around meningiomas.Among of them,the meningiomas with acro-osteolysis has the highest recurrence.
