     [摘要] 目的:提高晚期外伤性小脑幕裂孔下疝的影像学认识。方法：对临床上出现双瞳孔散大的103例重型颅脑损伤病例进行回顾性分析。第四脑室按狭窄程度分为闭塞、严重狭窄、轻度狭窄三组进行分析。结果：103例均有第四脑室闭塞或狭窄。其中第四脑室闭塞62例,重度狭窄28例,轻度狭窄13例; 死亡人数分别为56例(90.32%)、20例(71.43%)、5例(38.46%)。三组病例的死亡率统计学比较差异有显著性(χ2=18.40,P<0.01)。中脑和脑桥有明显变形、移位、旋转或边界消失。脑桥小脑角池一侧或双侧闭塞。结论：第四脑室闭塞或狭窄是诊断晚期小脑幕裂孔下疝的重要征象。第四脑室狭窄程度与患者死亡率有统计学相关性。
