目的分析和探讨囊性脑膜瘤的诊断和治疗。方法对1993年1月至2002年7月收治的18例颅内囊性脑膜瘤进行回顾性分析。结果肿瘤实质及囊壁全切11例,肿瘤全切加囊壁部分切除5例,肿瘤及囊壁大部分切除2例,无手术死亡和严重并发症。结论脑膜瘤由于囊性变而加速了病情发展,引起严重的临床症状,且往往误诊为其他性质的病变,应尽早手术,手术多能全切病变而取得较好的疗效。 Objective To analyze and explore the diagnosis and treatment of cystic meningioma. Methods 18 cases of intracranial cystic meningioma admitted from January 1993 to July 2002 were retrospectively analyzed. Results The tumors were completely resected in 11 cases. The resection of the tumor was partially resected in 5 cases and the resection of the tumor and wall was performed in 2 cases. There was no operative death and serious complications. Conclusion Due to cystic degeneration, meningiomas accelerate the development of the disease, causing serious clinical symptoms, and often misdiagnosed as other types of lesions, surgical resection should be as early as possible and surgery can achieve more effective lesions.
