目的：探讨第四脑室脉络丛乳头状瘤的诊断和显微外科治疗。方法：对1997年5月～2005年2月间收治的第四脑室脉络丛乳头状瘤14例进行回顾性分析,均采用枕下正中入路,6例通过切开小脑蚓部切除肿瘤,8例不切开小脑蚓部,而通过脉络膜下髓帆入路切除肿囊。结果：本组肿瘤全部切除13例,次全切除1例,无手术死亡和严重并发症。结论：脉络膜下髓帆入路是切除第四脑室脉络丛乳头状瘤的较好入路,显微外科技术是取得手术成功的关键。
Objective: To investigate the diagnosis and microsurgical treatment of the fourth ventricle choroid plexus papilloma. Methods: A retrospective analysis was performed on 14 cases of fourth ventricle choroid plexus papilloma admitted from May 1997 to February 2005, all under the suboccipital approach. Six cases were removed by incision of cerebellar vermis, 8 Cases do not cut the cerebellar vermis, and through the subrethral medullary sinus removal of cysts. Results: All the tumors in this group were resected in 13 cases and subtotally resected in 1 case. There was no operative death and serious complications. Conclusion: Subchoroidal medullary approach is a better approach for resection of the fourth ventricle choroid plexus. Microsurgical technique is the key to successful operation.
