Abstract:
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.
