摘要
目的 :回顾性分析脊椎滑脱的CT表现并讨论其检查方法、诊断和鉴别诊断。方法 :13例患者先行腰椎侧位扫描定位图像 ,采用与椎间盘平行的角度 ,自病变椎体的上一椎体下缘扫描至下一椎体上缘 ,层厚 5mm ,间隔 5mm。结果 :13例中真性滑脱 9例 ,假性滑脱 4例 ;发生在腰 5者 8例 ,腰 4者 5例 ;Ⅰ°滑脱 7例 ,Ⅱ°滑脱 6例 ;CT表现为“双边征”和椎体后下缘椎间盘对称性突出 ;伴峡部裂 7例 ,椎弓发育不良 2例 ,椎小关节增生 10例 ,椎管变形 8例 ,侧隐窝狭窄 2例 ,相邻椎间盘退变 10例。结论 :CT对诊断脊椎滑脱及评价脊椎滑脱的病因是一种有价值的检查方法。
Objective:To evaluate the CT findings of spondylolisthesis and to discuss the scanning technique and differential diagnosis of this abnormality.Methods:13 patients were scanned with axial CT using 5mm slice thickness and 5mm slice interval parallel to the intervertebral space.The area of scanning included the inferior surface of the vertebral body above the suspected pathological site to the superior surface of the vertebral body below the suspected pathological site.Results:The CT scans revealed the double margin sign and symmetrical protrusion of intervertebral disc at the level of the posterior inferior surface of the vertebral body.There were 9 cases of true spondylolisthesis and 4 cases of false spondylolisthesis.There were 7 cases of grade Ⅰ°of spondylolisthesis and 6 cases of grade Ⅱ°.The CT findings included spondylolysis(n=7),dysplasia of vertebral arch(n=2),hypertrophy of the joint facets(n=10),deformity of the spinal canal(n=8),stenosis of the lateral recess(n=2),and degeneration of the adjacent disc(n=10).Conclusion:CT scanning is a valuable method for diagnosis and evaluating the cause of spodylolisthesis
