目的 总结小脑脑桥角(CPA)区海绵状血管畸形(CMs)的临床表现、影像学特征及治疗特点.方法 2005年6月至2010年6月我科共收治CPA区CMs病例3例,进行报告.搜索MEDLINE上自1985年至2010年文献查到此类病例5例,进行文献复习.结果 文献复习的5例CMs临床表现为脑神经及小脑受累症状,但无脑干受压症状;影像见CMs均呈囊实性,与内听道及颅底硬膜无粘连;术中见CMs与周边结构有粘连,但可进行分离;手术治疗效果满意.本文报告的3例临床特征与之相符.结论 当CPA区见囊性病变与内听道及颅底硬膜无粘连时,应考虑到CMs的可能,显微外科手术切除多能获得良好的疗效.Abstract: Objective To investigate the clinical presentation, imaging features and treatment experience of cystic cavernous malformations ( CMs ) in the cerebellopontine angle ( CPA ) . Methods Three patients with the CMs of the CPA between 2005 and 2010 in our institute were summarised. Five patients from MEDLINE search of the English literature from 1985 to 2010 for CMs of the CPA were identified. We reviewed the characteristics of these 5 cases and our cases. Results Their presenting symptoms of 5 cases in the literature included headache, injury of cranial nerves in the CPA and cerebellar symptoms. But they did not show signs of brain stem compression. MRI and /or CT scans showed that the lesions in the eight cases of CMs all had solid and cystic components, and no adhesion with internal auditory canal and skull base dura mater was present in the CPA. Despite the fact that cystic CMs also involved cranial nerves, cerebellum, brainstem and arteries, they could be separated from these surrounding structures thanked to the presence of well - margined adhesion, which was contrary to solid CMs. We reported three cystic CMs of the CPA in our institute that was the same as the above. Conclusion Although cystic CMs of the CPA had no established imaging features, a diagnosis of CMs may be suspected when a cystic lesion is present in the CPA and does not involve internal acoustic meatus or dura matter of the skull base. Skillful microsurgical techniques will secure good outcomes for patients with cystic CMs in the CPA. 相似文献

目的初步分析胶质瘤细胞分泌的exosome蛋白组成,探讨胶质瘤来源exosome的潜在免疫调节功能,从而为进一步利用exosome对胶质瘤进行免疫治疗提供理论依据。方法采用差速离心法从U251胶质瘤细胞培养上清液和Ⅲ级星形胶质瘤囊液中分别提纯exosome,用透射电镜鉴定;利用二维电泳分离、分析exosome内蛋白质,并用质谱技术鉴定了部分蛋白质。结果胶质瘤细胞可以产生exosome,其平均直径约100 nm。二维电泳图显示U251细胞分泌的exosome含有270个蛋白点,与数据库相符的有66个;而来自Ⅲ级星形胶质瘤囊液的exosome含有242个蛋白点,与数据库相符的有60个;两者有130个蛋白点在等电点和表观分子量方面相同,其中包含HSP70、RNA结合蛋白、核酸外切酶、MHCI及MHCII类分子等。部分蛋白质点质谱鉴定结果为hCG、低密度脂蛋白、T细胞受体等。结论胶质瘤细胞可分泌exosome,其一般特性与已报道的exosome一致,其蛋白组成与其他细胞来源的exosome具有共性,体内和体外培养的胶质瘤细胞分泌的exosome的蛋白质组成具有同源性与差异性。胶质瘤细胞源的exosome具有一定的免疫调节功能,可以为胶质瘤免疫治疗提供理论基础。 相似文献

近年来,随着栓塞材料及技术的不断发展,尤其是Onyx胶的出现,使得动静脉畸形的血管内介入治疗更广泛的用于临床。但栓塞治疗过程中仍伴随着诸多风险,比如发生正常灌注压突破、栓塞后出血以及导管滞留体内等[1]。虽然每名医生在血管内介入治疗动静脉畸形时都可能遇到这些情况,但关于这些并发症的发生率、原因及结果的了解还不多。吉林大学第一医院神经外科自2003年6月至2008年6月期间,共使用Onyx胶栓塞颅内动静脉畸形58例,其中7例出现并发症,现将治疗结果报告如下。 相似文献

颅底肿瘤切除术后发生幕上远隔部位硬膜外血肿并不多见,即使发生也多为单侧[1-3],而发生于双侧对称的急性硬膜外血肿则较为罕见,一旦发生极为凶险. 相似文献
