目的:探讨圆锥马尾部室管膜瘤的诊断及手术治疗特点。方法:分析13例经手术治疗的圆锥马尾部室管膜瘤患者的临床表现、影像学特征和手术治疗疗效。结果:13例患者中MRI对圆锥马尾部室管膜瘤作出定性诊断的占53.8%。全组患者均行手术治疗,获肿瘤全切除10例,次全肿瘤切除3例。术后所有患者症状体和体征均明显改善。结论:圆锥马尾部室管膜瘤的MRI术前定性有一定困难,需与星形胶质细胞瘤、神经鞘瘤及胆脂瘤等鉴别。显微手术技术的应用和肿瘤全切除是获得满意疗效的关键。
Objective: To investigate the diagnosis and surgical treatment of conus pachytene ependymoma. Methods: The clinical manifestations, imaging features and the curative effects of surgical treatment of 13 patients with conical cauda equina ependymoma were analyzed. Results: 13.8% of the 13 patients had qualitative diagnosis of conus cauda equina. All patients underwent surgical treatment, the total removal of the tumor in 10 cases, subtotal tumor resection in 3 cases. All patients after surgery symptoms and signs were significantly improved. CONCLUSION: Conical cauda equina erosional MRI has some difficulties in the preoperative MRI. It is necessary to differentiate it from astrocytoma, schwannoma and cholesteatoma. The application of microsurgical techniques and total tumor resection is the key to obtaining satisfactory results.
