摘要
目的 探讨后颅窝血管母细胞瘤的诊断和显微手术治疗。方法 回顾安徽医科大学第一附属医院神经外科1995年10月，2005年12月间73例经显微手术并经病理证实的后颅窝血管母细胞瘤的临床资料，并从影像学特点，诊断，显微手术治疗和术中注意事项等方面予以分析。所有手术均在显微镜下进行。结果 肿瘤常见发病年龄为20-45岁，常见发病部位是小脑半球。在显微镜下行肿瘤全切除68例。术后死亡8例，其中4例位于延髓，3例位于小脑蚓部，1例位于小脑半球。2例全切除后复发。结论 CT、MRI检查是明确诊断的必要手段，大囊及小结节异常对比强化是血管母细胞瘤的特征性影像学表现；实质型肿瘤和位于延髓的肿瘤手术风险大。
Objective To study the diagnosis and microsurgical treatment of posterior fossa hemangioblastoma. Methotis The clinical data of 73 patients with posterior fossa hemangioblastoma from October 1995 to December 2005 were retroperativly analysed. The clinical data includes clinical features , neuroimaging , diagnosis , and operative waining events of the hemangioblastoma. All cases were treated by microsurgery and verified by pathology. Results The tumors occurred mainly in patients between 20 to 45 years of age, most tumors were in hemisphere of cerebellum. The tumors of 68 patients were totally removed; 8 patients were died with 4 cases in medullary, 3 cases invermis , and 1 in hemisphere of cerebellum. 2tumors were recurrent 3 and 5 years later after operation. Conclusion CT and MRI is necessary for diagnosis. The fellow phemomena is thecharacteristic of neuroimaging of most tumor： a great cystic areas with the a small solid mural nodule ,the small solid mural nodule usually is enhanced after injection of contrast media , while the area of the cystic may not be enhanced . It is dangerous to remove the solid tumor or the tumor in medullary.
