颅内脑膜瘤具有良性肿瘤的生物学特性,但有少部份肿瘤可复发,本院在近14年中经手术及病理证实的颅内脑膜瘤70例。位于矢窦旁区18例,大脑突面17例,蝶骨嵴9例,鞍结节6例,大脑镰-小脑天幕区3例,镰旁5例,脑室内3例,眶内2例,窦汇区、溴沟、天幕裂孔游离缘、大脑半球纵裂间、小脑天幕 (向幕上下生长)、岩尖、枕大孔区各一例。肿瘤切除范围按Simpson分类分为五级:Ⅰ级 (根治术)13例,无复发;Ⅱ级 (肿瘤肉眼全切除,瘤基部电凝烧灼) 24例,4例复发,Ⅲ级 (次全切除) 24例,5例复发;Ⅳ级(部份切除) 9例,未随访,V级(减压术)0例。70例中术后复发9例,复发率12.86％,其中7
Intracranial meningioma has the biological characteristics of benign tumors, but a small number of tumors can be relapsed, the hospital in the past 14 years by surgery and pathology confirmed intracranial meningioma in 70 cases. There were 18 cases of parasagittal region, 17 cases of brain protrusion, 9 cases of sphenoid ridge, 6 cases of saddle nodules, 3 cases of falx nodules, 3 cases of falx nocturnal cerebellum, 5 cases of falx, 3 cases of intracerebroventricular, 2 cases of orbital, Douhui District, bromine groove, the cantilever hole free edge, between the cerebral hemisphere longitudinal crack, the cerebellar sky (growing up and down the curtain), the rock tip, a large hole in the occipital region of a case. According to Simpson’s classification, the tumor resection scope was divided into five grades: 13 cases of grade Ⅰ (radical operation) without recurrence, 24 cases of grade Ⅱ (total macroscopic resection of tumor, coagulation cautery of tumor base), 4 cases of recurrence and Ⅲ grade ) 24 cases, 5 cases relapsed; Ⅳ (partial resection) in 9 cases, were not followed up, V class (decompression) in 0 cases. Of the 70 cases, 9 cases were relapsed after operation, the recurrence rate was 12.86%, of which 7 cases
