摘要
目的:探讨CT及MR诊断早期小脑幕疝的标准及临床价值。方法:选取79例无瞳孔改变的偏侧占位效应明显的患者与100名无明显颅脑症状及体征的志愿者作为对照,研究诊断早期小脑幕疝的标准及临床价值。结果:对照组100名志愿者经CT及MRI检查未发现小脑幕疝征象。实验组CT发现小脑幕疝49例,MR发现57例。其中平行斜坡垂线CT扫描发现41例,平行于斜坡CT扫描发现19例。结论:平行斜坡垂线CT及MRI均可对早期小脑幕疝做出诊断,对指导制定治疗方案具有重要意义。
Objective： To study the diagnostic criteria and meaning of early cerebellar transtentorium herniation. Methods： 79 cases who had no pupil change and had obvious massing effect as study objects. 100 volunteers without any cranial symptoms and signs as contrast objects.Results：No any sign of transtentorium herniation were found by CT and MRI in contrast objects, 49 patients who had soft mass below transtentorium herniation connecting with superior transtentorium brain tissue were found by CT and 57 cases were found by MR in study objects. 41 cases were found by CT which ventral to clivus and 19 cases were found by CT which parallel to clivus. Conclusion： CT and MRI which vertral to clivus should enable to diagnose early transtentorium herniation,it is important to make treatment plan.
