Abstract： 目的通过回顾分析颅内血管外膜细胞瘤的临床资料,探讨其相关的诊断依据及治疗方法.方法对近5年我院收治的60例颅内血管外膜细胞瘤病人的一般资料,临床特点,影像资料,病理表现及治疗结果进行总结分析.结果发病率男性大于女性,以青壮年占多数,平均病程11个月;CT显示肿瘤呈略高密度影,无钙化;MR显示肿瘤多呈分叶状,有血管流空信号影,瘤内有坏死囊变和窄基底,"硬膜尾征"少见,T2WI呈等高混杂信号,注射对比剂后在T1WI上呈不均匀明显强化;所有病例均被行手术加术后放疗,其中28例第1次术后随诊结果显示:肿瘤全切组平均随访时间28个月,复发率6%;肿瘤近全切除组平均随访时间27个月,复发率71%;肿瘤大部切除组平均随访时间19个月,复发率100%.结论如果CT显示略高密度影和无钙化及MR显示肿瘤呈分叶状;T2WI呈等高混杂信号和无"硬膜尾征"时,应考虑血管外膜细胞瘤的诊断.肿瘤切除的程度是决定肿瘤复发的关键因素,手术应做到尽量全切肿瘤,术后应常规辅以放射治疗,可获得较好的预后.
