摘要目的 探讨顶盖胶质瘤的治疗策略.方法 回顾分析我院2003年至2007年治疗的12例顶盖胶质瘤患者的临床、影像学和病理资料.结果 肿瘤完全切除3例,大部切除9例.低级别胶质瘤11例,高级别胶质瘤1例.平均随访51个月,10例病情稳定、肿瘤无进展;1例术后死亡;1例因肿瘤进展死亡.结论 大多数顶盖胶质瘤生长缓慢,若患者无脑积水或脑积水解决后,应长期随访MRI,如患者临床症状进行性加重、肿瘤进行性增大(直径＞2 cm)、瘤内有明显强化或出现侵袭性生长时,可采取手术治疗.

abstractsObjective To explore the management strategy of tectal gliomas. Method From 2003 to 2007, twelve cases of tectal gliomas were treated in our department. We retrospectively analyzed their clinical characteristics,imaging features and pathologies, and reported the results after a mean follow- up of fifty - one months. Results Three tumors were completely removed, nine were partially removed. Eleven tumors were low grade gliomas,one was a high grade glioma. One patient died after the surgery, one patient died of tumor progression, and other ten patients were stable without tumor progression during the follow - up study. Conclusions As most tectal gliomas have an indolent nature in clinical course,we recommend for patients without hydrocephalus or with relieved hydrocephalus, a long - term MRI follow - up should be conducted ;for patients with worsening neurological deficits or with a progressing tumor(larger than 2 cm in diameter or with significant enhancement),a surgery should be performed.
