Intracranial meningiomas and epilepsy: incidence, prognosis and influencing factors

In a retrospective study of a consecutive series of 222 surgically treated meningiomas, it was found that 26.6% of the patients presented epilepsy as their initial symptom. In this group, surgical excision of the intracranial meningiomas stopped the epilepsy in about 62.7% of the patients. But approximately one-fifth of the patients with intracranial meningiomas and no history of preoperative epilepsy developed new onset postoperative seizures. Of the patients with early onset of postoperative epilepsy, epilepsy appeared in 66.7% within first 48 h after surgery. Of the patients with postoperative epilepsy, 71.2% were seizure-free following 1 year of anticonvulsant therapy. Regarding preoperative existing factors, intracranial meningiomas located at supratentorium, convexity, and with evidence of or severe peritumoral edema significantly contributed to preoperative epilepsy. And in patients with preoperative epilepsy, those tumors with evidence of or severe perifocal edema and cerebral edema at the operative site were significantly more likely to suffer from postoperative epilepsy.     

上矢状窦旁脑膜瘤术后复发相关因素分析

Surgical treatment of parasagittal and falx meningiomas

BACKGROUND AND PURPOSE: We present our experience with surgery of parasagittal and falx meningiomas with special consideration of surgical outcome and risk of recurrence. MATERIAL AND METHODS: A series of 87 consecutive patients surgically treated for parasagittal and falx meningiomas is reported. 50 patients had parasagittal meningiomas and a further 37 had falx meningiomas. Meningioma invaded the superior sagittal sinus in 21 cases. According to Simpson's scale, 25 procedures were Grade I resection, 55 were Grade II resection and 7 were Grade IV resection. Among 21 patients with parasagittal meningiomas invading the sagittal sinus, radical resection of the tumour and invaded part of sinus was made in 9 cases. RESULTS: Seven patients were severely disabled and 4 patients died after the surgery whereas 76 patients had satisfactory outcome on discharge. At the time of analysis, 14 patients had shown evidence of recurrence. Male gender, partial removal of meningioma (Simpson Grade IV) and bilateral falx meningioma had a statistically significant influence on recurrence. There were no tumour recurrences following radical resection of the tumour and invaded part of sinus, but two postoperative deaths due to haemodynamic complications were noted. In the other 12 patients, meningiomas were removed but sinus infiltration was left in place; the postoperative period was uneventful but the rate of clinically important regrowth in this group of patients was 25% in long-term follow-up. CONCLUSIONS: Rate of recurrence of parasagittal and falx meningioma significantly increases in cases of non-radical resection of tumour. Aggressive surgical treatment presents several hazards and carries an increased risk of unsatisfactory outcome; the risk of recurrence, however, is significantly decreased.     

幕上脑膜瘤术后早期癫痫的临床分析

目的探讨影响幕上脑膜瘤术后早期癫痫发生的相关因素。方法回顾性分析2001年1月至2006年12月间经手术治疗的173例幕上脑膜瘤患者,分析其临床特征、外科手术情况、术后并发症、术后早期癫痫的发生情况及其关系。结果术后发生早期癫痫14例,占8.09%。其中全面性发作3例,局灶性发作11例。6例发生于术后24小时内,8例发生于术后2～7天。10例肿瘤次全或大部切除、30例术中发生皮层或皮层血管损伤、25例术后瘤腔出血、69例脑水肿、56例术后水电解质紊乱,各组中发生术后早期癫痫例数分别为2例、4例、5例、8例和9例。结论幕上脑膜瘤的术后早期癫痫的发生与瘤体大小、手术操作技巧、肿瘤切除程度、术后并发症等因素密切相关。     

脑膜瘤伴周围脑水肿60例分析

目的:研究脑膜瘤伴周围脑水肿的临床与手术特点。方法:本文报道脑膜瘤伴周围脑水肿60例,占同期收治脑膜瘤(130例)的46.2％。对其临床特点、CT、脑血管造影(CAG)与瘤周脑水肿手术所见进行了讨论。结果:CT扫描显示瘤周低密度或部分低密度影为脑膜瘤瘤周脑水肿区。CAG显示该部位血供主要来自颈内动脉软脑膜支,手术所见,在脑膜瘤周围与脑组织软脑膜层之间存在广泛粘连,术中分离肿瘤时出血较多。相反,CT扫描显示肿瘤周围没有低密度改变。CAG检查该部位血供主要来自颈内动脉硬脑膜支,因肿瘤同围无粘连、术中损伤小、出血也少。本组脑膜瘤全切34例,大部切除26例。结论:脑膜瘤瘤周脑水肿产生的重要因素有:①术前肿瘤血运丰富,有软脑膜支供血;②肿瘤周围及脑表面静脉切断后,该处静脉回流不畅,侧支循环在短期内尚未建立。矢状窦旁脑膜瘤手术时要保护上矢窦和中央静脉,对防止术后脑水肿相当重要。应用显微外科技术,可明显提高手术效果。

Papillary meningioma: an aggressive variant meningioma with clinical features and treatment: a retrospective study of 10 cases

Introduction: Papillary meningioma is a rare subtype of malignant meningiomas. The aim of this retrospective study was to investigate the clinical, radiological, histopathological features and prognosis for papillary meningioma at our institutions. Materials and methods: Ten patients with clinically, radiologically and histopathologically confirmed papillary meningiomas were treated at our hospitals. The clinical data, imaging characteristics, histopathological features, surgical treatment and postoperative follow-up, were analyzed retrospectively. Results: The patients with a mean age of 36.9 years at the time of their initial operations. The papillary meningiomas were predominantly located in the convexity (n = 6). At their initial operation, six patients underwent gross total resection and four patients underwent subtotal resection. The mean post-operative follow-up period was 42.6 months (range: 12–90 months). Six patients underwent multiple surgical resections. The mean time to first recurrence was 21.5 months. On magnetic resonance imaging scan, marked enhancements and dural tail signs were displayed in all lesions. All lesions showed peritumoral edema. Cysts were seen in four lesions. Bone hyperostosis or destruction was seen in six lesions. Cerebrospinal fluid dissemination was seen in three lesions. Incomplete surgical resection was associated with recurrence. MIB-1 labeling index was associated with progression-free survival for patients (p = 0.0442). Conclusions: Papillary meningioma has a tendency to present in middle-aged patients, and it has specific clinical and histopathological characteristics. MIB-1 labeling index and the extent of resection might predict the recurrence. Cystic formation, peritumoral edema, osseous change and CSF dissemination might be neuroimaging characteristics of papillary meningioma, especially in recurrence papillary meningioma.
