颅内室管膜下瘤的诊断和显微外科治疗(附33例报告)

目的 探讨颅内室管膜下瘤的临床特点和治疗方法.方法 回顾性分析北京天坛医院收治的33例室管膜下瘤患者的临床特点、诊断和治疗.结果 本组33例,男19例,女14例;年龄2～54岁,平均27.4岁;第四脑室13例,侧脑室18例,脑内2例.MRI T1WI呈等或略低信号,T2WI呈高信号;22例无强化,11例呈片状、结节或条索样轻度强化.侧脑室18例,手术全切13例,近全切除5例.第四脑室13例,手术全切3例,近全切除7例,大部切除3例.脑内2例均近全切除.结论 颅内室管膜下瘤少见,影像学有显著特征,有助于术前诊断,显微外科治疗手术全切除预后好.

Abstract：

Objective To explore the clinical characteristics and treatment of intracranial subependymoma.Method 33 patients with intracranial subependymoma treated with microneurosurgical management at Beijing Tiantan Hospital from 1998 to 2008 were analyzed retrospectively.Results In this serials,19 patients were in male and 14 patients in female.Tumors located in the lateral ventricles in 18 cases,located in the fourth ventricle in 13 cases,intra-brain tissue in 2 cases.On MRI scans,the tumors showed iso/hypointensity on T1-weighted and hyperintensity on T2-weighted images.On enhanced scans,the tumors showed no enhancement or only slightly enhancement.Tumors located in the lateral ventricles,were totally removed in 13 cases and subtotal in 5 cases;tumors located in the fourth ventricle,were totally removed in 3 cases, subtotally in 7 cases and partial in 3 cases; tumors were subtotally removed in 2 cases in intra-brain tissue type.Conclusions MRI may contribute to diagnose the intracranial subependymoma and surgical management.Radical resection usually contributes to a good outcome.
