摘　　要：目的　研究因椎体因素致假性腰椎间盘膨出的CT征象。资料与方法　对 87例腰椎间隙上下椎缘平面大小不一的CT扫描图像进行分析。在CT轴位图像上测量椎间盘与相邻椎缘平面最大横径和在定位像上测量椎间盘上下缘椎体的矢径 ,比较其大小。结果　 6 7例诊断为假性腰椎间盘膨出 ,其CT表现与椎间盘膨出相同 ,但膨出的椎间盘不大于相邻较大椎缘平面 ,且无腰椎间盘膨出的伴随征。结论　CT诊断腰椎间盘膨出时 ,应注意膨出的椎间盘与相邻椎体平面大小的比较 ,以排除假性腰椎间盘膨出。Objective To discuss CT manifestations of pseudo bulging of lumbar intervertebral disc due to the size factors of adjacent vertebral body plane. Materials and Methods CT findings of 87 lumbar intervertebral disc, which adjacent vertebral bodies had different sized margin planes, were retrospectively analyzed. On axial CT images, the maximum transverse dimension of the intervertebral disc and the adjacent vertebral margin planes, as well as the longitudinal height of the adjacent vertebral bodies on scanogram, were measured. The results were compared.Results Sixty seven patients were diagnosed as pseudo bulging, who showed the same CT sings as true lumbar intervertebral disc bulging, but the size of the 'bulging' disc was smaller than the adjacent vertebral margin planes and the patients showed no symptoms and signs of disc bulging clinically. Conclusion When diagnosing disc bulging, the size of the questioned disc should be compared with the size of the adjacent vertebral margin planes in order to exclude pseudo-bulging of the lumbar intervertebral disc.
