延髓髓内血管母细胞瘤的诊断与治疗

目的 探讨延髓髓内血管母细胞瘤的诊断与治疗。方法 回顾性分析7例患者的MRI表现及其手术治疗的效果。结果 这类肿瘤在MRI上可分为二型：A、实体型，B、囊肿型。所有患者均经手术全切除肿瘤，并经病理证实为血管母细胞瘤。术后患者神经系统状态好转者6例，加重1例。结论 颈髓MRI能对延髓髓内血管母细胞瘤作出定位、定性诊断，并可将其分型，以利选择不同的手术方法。延髓髓内血管母细胞瘤宜行积极手术治疗，手术方法随肿瘤类型不同而各异，应在离断供血动脉后沿正确的界面分离，最后切除肿瘤。

Diagnosis and treatment of intramedullary hemangioblastoma of medulla oblongata

Objective To probe into the diagnosis and the treatment of intramedullary hemangioblastoma of of medulla oblongata. Methods The signs of MR imagings , and the methods and the results of operations were analysed in 7 patients with the tumor. Rusults On MRI , the tumors can be divided into two types : A. Solid type and B. Cystic type. All the patients underwent total tumor removal. Resected tumors were hemangioblastomas that were all confirmed by histological examinations. After operation , neurological status was improved in 6 patients and aggravated in 1. Conclusions For intramedullary hemangioblastoma of medulla oblongata , MR imagings can make out the diagnosis of localization and the nature , and classification. The classficationn is conductive to selecting appropriate operative method. Intramedullary hemangioblastoma of medulla oblongata is amenable to aggressive surgery. Operative methods varied with the different type of the tumor. It is the most important that dissection is performed along the innterface and the tumor is removed after it is devascularized.
