腰椎间盘椎体内突出的CT诊断及相关分析

摘要

Objective To investigate the computer tomography (CT) characteristics and classification of lumbar intervertebral disk intraosscous hemiation (IDIH), and to analyze the relationship between CT characteristics and the selection of treatment. Methods Eight patients with IDIH (4 males and 4 females, 28~74 years old with a mean of 44.2) were enrolled in this study. L3~S1 intervertebral spaces and discs of the patients were scanned by CT. One patient with suspicious lesion were further scanned for inferior plane of intervertebral space Results All the patients were observed with lumbar IDIH by CT, including 6 cases locating at L4-5 and 2 cases locating at L5~S1. All the patients displayed intraosseous defect, of which 6 cases was at the inferior edge of L4 vertebrae and 2 cases at the inferior edge of L5 vertebrae. The defects of 4 cases were round and 4 cases were irregular, which were filled with disc. Meanwhile, separated bony mass (n=4), irregular endplate of (n=4) and wedge-shaped vertebra (n=2) could be observed at the same level. Conclusion CT should be regarded as one of reliable ways for the examination and diagnosis of lumbar IDIH, which play important role in the selection of clinical treatment.%目的 探讨腰椎间盘椎体内突出的CT特征和分类及其与临床治疗之间的关系.方法 本组收集8例患者(男4例,女4例,年龄28～74岁,平均44.2岁),全部行L3-S1椎间隙CT扫描检查,其中1个可疑椎间盘向椎间隙下方加扫薄层.结果 8例患者CT都显示椎间盘椎体内突出,发生于L4～5椎间盘6例,L5-S1椎间盘2例.CT表现为椎体内缺损8例,其中,缺损呈圆形4例,不规则形4例,椎体后缘翘起4例,椎体后缘离断4例,椎管狭窄1例.结论 CT是诊断腰椎间盘椎体内突出的可靠方法之一,对临床治疗方法的选择和个性化治疗方案的制订很有帮助.
