简介:背景和目的:脑肿瘤患者在高原地区的临床表现有其特点。本文对西藏高原脑肿瘤发生急性脑疝的临床表现、诱发因素、辅助检查、治疗和结果进行分析讨论。方法:回顾性分析1999年1月至2005年12月.经手术治疗的11例急性脑疝的脑肿瘤病例。其中男性3例,女性8例,年龄31~52岁,平均38.9岁。汉族10例。8例为急进高原,2例暂住3个月;藏族1例,从海拔4500米到3700米后发病。结果:所有患者均接受了颅脑CT检查,肿瘤直径3~6cm,其中3例接受了MRI检查。8例急诊行开颅肿瘤切除术,3例经抗癫痫、脱水、对症治疗后择期手术,无手术死亡。肿瘤病理诊断均为脑膜瘤。结论:头痛、呕吐、癫痫发作、昏迷是高原地区急性脑疝最常见的临床症状,从平原地区急进高原是最常见的诱因。颅脑CT是最快速准确的诊断方法。经抗癫痫、脱水等治疗意识好转不明显者,应尽早手术。
简介:Sclerosing上皮状的纤维肉瘤(SEF)是纤维肉瘤的稀罕、糟糕定义的变体,但是对与穷人一起的化疗和进步通常感觉迟钝预后。我们报导irinotecanhydrochloride(CPT-11)的奇妙的效果在rescuing的化疗在几个治疗方法以后经历了复发的有从突现的状况的不正常的SEF的一个病人。CPT-11的小剂量予病人被以,与哪个,表面的质量(颈的淋巴节点)的尺寸逐渐地减少了在5天内由肉眼观察了。X射线和CT图象在肿瘤的尺寸证明了显著减小。CPT-11为这个好攻击的肉瘤的治疗是珍贵的。处于肉瘤压迫引起的紧急情况的状况,管理topoisomerase我禁止药的可容忍的小剂量能是一种有益的选择。
