摘　　要：目的分析脑外伤并天幕疝的CT表现,探讨斜坡垂线扫描法对检出外伤合并天幕疝的价值。方法对156例脑外伤患者应用斜坡垂线扫描法进行研究。结果斜坡垂线扫描图像上,72例显示天幕疝,其CT表现为:与颞叶脑组织相连的小脑幕内侧环池内软组织密度影,患侧环池增宽。未显示天幕疝的84例病人无患侧环池扩大。平行OM线扫描图像上,72例患者颞叶与小脑幕切迹的关系无法确定。结论斜坡垂线扫描法对检出外伤合并天幕疝有重要价值。外伤病人出现昏迷或颅内压增高时应行斜坡垂线扫描。Objective To explore the value of vertical to clivus CT scanning in diagnosing tentorial hernia and to analyze the CT findings of tentorial hernia in the patient with brain trauma. Methods Vertical to clivus CT scaning were performed in 156 cases with brain trauma.Results Vertical to clivus scanning method directly demonstrated the temporal transtentorial hernia in 72 of 156 patients with unilateral high intracranial pressure, but the orbitomeatal line scanning method was not able to show this direct finding. The CT findings of hernia were the tissue of temporal lobe appeared in the cisterna ambiens inside the tentorium accompanied by enlarged cistern on the involved side. No change of cistern were seen in 84 cases.Conclusion The scanning method with vertical to the clivus is effective in detecting tentorial hernia in the patient with cerebral trauma, it should be performed in the patient with cerebral trauma and increased intracranial pressure.
