摘　　要：目的探讨侧脑室内室管膜下瘤的诊治策略。方法回顾性分析13例侧脑室内室管膜下瘤病人的临床表现、影像学表现及显微外科手术治疗效果。结果该病多见于中年人,以颅内压增高为主要临床表现;MRI显示:T2WI多呈高信号,T1WI上多表现为低、等信号,增强扫描大多无明显强化。肿瘤全切除12例,次全切除1例。术后死于并发症1例。对12例随访0.5～11年,均未见复发。结论侧脑室内室管膜下瘤影像学表现具有一定特征,是术前诊断的重要参考;显微手术切除肿瘤是最佳的治疗手段,预后良好。Objective To investigate the strategy for diagnosis and microsurgical treatment of subependymoma in the lateral ventricles. Methods The clinical manifestations, imaging appearances and microsurgical outcomes in 13 patients with subependymoma in the lateral ventricle were analyzed respectively. Results Subependymoma in the lateral ventricle occurred mainly in middle-aged people with increased intracranial pressure as the main clinical manifestation. Most of the tumors appeared hyperintense on T2-weighted images （T2WI）, hypointense or isointense on T1-weighted images （T1WI） and no marked enhancement after intravenous contrast material injection. Total resection was achieved in 12 patients and subtotal resection in one. One patient died of postoperative complications, and no recurrence was found in the other 12 patients during a follow-up period of 0.5 to 11 years. Conclusion Subependymoma in the lateral ventricle is of characteristic changes on imaging appearances, which provides an important reference for preoperative diagnosis. Microsurgical resection is the most effective therapeutic tool for the tumor with favorable prognosis.
