【摘要】 目的探讨原发脑室内神经鞘瘤的临床特点及治疗。方法回顾性分析2例原发脑室内神经鞘瘤的临床资料,并结合文献进行分析。结果 2例均为青年病人,影像学检查示脑室内占位明显,术前误诊为其他病变,开颅手术全切肿瘤,术后病理诊断证实为神经鞘瘤。术后随访1～3年,未见肿瘤复发。结论原发脑室内神经鞘瘤非常罕见,基本为良性病变,影像表现多样,不具特异性,可出现囊肿、周围水肿、钙化、伴脑积水等多种表现,增强扫描均有不同程度强化,术前易误诊,手术全切率高,预后良好。更多还原

【Abstract】 Objective To analyze the clinical characteristics and the prognosis of primary intraventricular schwannomas(PIVS).Methods The clinical data of 2 patients with PIVS were analyzed retrospectively and the relative literature was reviewed. Results The two patients with PIVS were all young. The examination of brain imaging suggested that there were intraventricular occupying lesions in the patients, in whom the tumors were completely resected by craniotomy. The schwannomas were proved pathologically. The followingup from 1 to 3 years after the surgery showed that no tumors recurred in all the patients. Conclusions PIVS are very rare and basically benign. The imaging features are diverse and are not specific. Cysts, peritumorous edema, tumorous calcification and associated hydrocephalus may be found on cerebral imagings. CT or MRI scanning shows that there is homogeneous or heterogeneous enhancement after contrast application in PIVS. Preoperative misdiagnosis is made easily, but the total resection rate is high and the prognosis is good in the patients with PIVS.更多还原
