侧脑室内脑膜瘤20例临床分析

Diagnosis and treatment of lateral ventricular meningioma

目的探讨侧脑室内脑膜瘤的诊断和手术治疗方法，以提高对其的诊治水平。方法回顾性分析我院自2000年3月至2007年9月手术治疗的20例侧脑室内脑膜瘤患者临床资料，并复习相关文献。结果本组患者均行手术，肿瘤全切除19例，大部分切除1例。术后恢复良好19例，中度残疾1例，无手术死亡病例。13例患者随访4个月至6年，有2例患者肿瘤复发，其余患者头痛症状消失，无恶心呕吐，视力好转，失语及偏瘫症状有不同程度好转。结论侧脑室内脑膜瘤术前诊断依赖CT及磁共振成像检查，选择适合的手术入路，采用显微技术可以全切除肿瘤，保护神经功能完整。

Objective To explore the method of detection, differentiation and surgical treatment of lateral ventricular meningioma to improve the diagnosis and treatment. Methods Twenty patients with lateral ventricular meningioma from March 2000 to September 2007 were analyzed retrospectively and the relative literature was reviewed. Results All patients performed craniotomy. 19 had total removal of tumor and 1 had subtotal removal. 19 had good recovery and 1 was moderate disabled at discharge. No surgical related mortality occured. 13 patients had followed-up between 4 months to 6 years. 2 patients experienced tumor recurrence and others showed disappearance of headache, nausea and vomiting, improvement of muscle power, visual and linguistical ability with different degrees, Conclusion Preoperative diagnosis of lateral ventricular meningioma depends on CT or MRI. Neurologic function can be well preserved after total removal of tumor via optimal approach with microsurgical technique.
