目的：正确认识正常大脑镰与纵裂池出血的CT表现特点，以提高纵裂池出血CT诊断的准确性，减少漏疹或误诊。方法回顾性收集经CT检查确诊为纵裂池出血35例。另收集我科正常颅脑CT80例。均行轴位CT扫描，将大脑镰与纵裂池以及胼胝体和侧脑室为界分为上、前、后三部分[1]进行对比分析。结果正常大脑镰表现为细现状高密度影，纵裂池出血则表现为呈一较正常大脑镰粗的高密度影，边缘模糊，少数呈密度“之”字征。正常镰旁脑脊液间隙消失。天幕切迹缘增宽。结论 CT鉴别诊断正常大脑镰与纵裂池出血有重要价值。
目的：正確認識正常大腦鐮與縱裂池齣血的CT錶現特點，以提高縱裂池齣血CT診斷的準確性，減少漏疹或誤診。方法迴顧性收集經CT檢查確診為縱裂池齣血35例。另收集我科正常顱腦CT80例。均行軸位CT掃描，將大腦鐮與縱裂池以及胼胝體和側腦室為界分為上、前、後三部分[1]進行對比分析。結果正常大腦鐮錶現為細現狀高密度影，縱裂池齣血則錶現為呈一較正常大腦鐮粗的高密度影，邊緣模糊，少數呈密度“之”字徵。正常鐮徬腦脊液間隙消失。天幕切跡緣增寬。結論 CT鑒彆診斷正常大腦鐮與縱裂池齣血有重要價值。

Objective To recognize correcting Ctappeurances of the normal cerebral falx(CF) and the hemorrhage of the interhemispheric Fissure cistern (IHFC).so as to improve accuracy of interhermipheric ifssure hemorrhage CT diagnosis, reduce misdiagnose.Methods 35 cases of hemorrhage of IHFC had been collectell,which were delimiting diagnosable by CT in addiction 80 cases of normal.skull.All travel axle’s CT scanning, The cerebral falx and the interhemispheric ifssure cistern were divied into superior ,anterior and posterior segment by the corpus cellosum.Results the normal falx cerebral presented as a thinning hyper-dense line, hemorrhage in the interhemispheric ifssure cistern presented as a widening hyper-dense line;edge obscured, a few presented zigzag hyper-dense.naomal interval disappear, thickening of the tent rid incisures margin, Conclusion CT scan is of important value in differential diagnosing normal falx cerebral and hemorrhage of the interhmispheric ifssures cistern.
