摘要
目的探讨腰椎椎体后缘软骨结节（LPMN）的CT诊断价值，以提高对本病的认识并做好鉴别诊断。方法对本院5年来收治的35例腰椎椎体后缘软骨结节患者的临床表现和CT特征进行了回顾性分析。结果典型的腰椎椎体后缘软骨结节CT表现为：①椎体后上缘或后下缘类圆形或不规则形骨质缺损，边缘致密硬化；②缺损后方有一小骨块突入椎管，完全游离或部分与椎体相连；③对应层面的硬膜囊及神经根受压；④多伴有椎间盘突出并继发椎管狭窄。结论CT检查能够明确地诊断腰椎椎体后缘软骨结节，为临床治疗提供可靠的依据。
Objective To evaluate the CT diagnosis value of lumbar posterior marginal intraosseous cartilaginous nodes （LPMN） , in order to improve the understanding of the disease and do with the differential diagnosis. Methods Clinical manifestations and CT features of LPMN in 35 eases hospitalized in the last five years were analyzed retrospectively. Results The classical CT features of LMPN includes ： （1） Osseous defect with sclerotic margin in the posterior - superior or posterior - inferior margins of centrum ; （2） Behind the defect area, bone fragments protrude into the spinal canal, totally dislocated or partially joined with centrum; （3） The dural sac and nerve root of corresponding dimension compressed;（4） The compression is accompanied by lumbar disc herniation and spinal canal stenosis. Conclusions LMPN can be definitively diagnosed by CT scan, which provides reliable basis for the clinical treatment.
