摘　　要：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。Objective To recognize correcting Ctappeuranccs of the normal cerebral thlx（CF） and tile hemorrhage of the interhemispheric Fissure cistern （IHFC）.so as to improve accuracy of interhermipheric fissure 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 fissure cistern were divied into superior ,anterior and posterior segment by the corpus cellosumResults the nonllal falx cerebral presented as a thinning hyper-dense line, hemorrhage in the interhemispberic fissure 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 fissures cistern .
