目的 :分析腰椎骨内软骨结节的CT征象 ,探讨其起因及形成机制。材料与方法 :收集 11例腰椎骨内软骨结节病例资料 ,扫描定位为上椎体下缘终板平面、椎间盘平面和下椎体上缘终板平面 ,发现病变后在终板平面上或下追加扫描 1～2个层面 ,扫描层厚 2mm～ 5mm。结果 :腰椎骨内软骨结节的CT征象可表现为三种类型 :许莫氏结节、结节内骨块型和结节后骨块型。结论 :腰椎骨内软骨结节好发于青壮年 ,由椎间盘髓核疝入椎体松质骨内而形成 ,是一种独立存在的疾病 ,先天发育缺陷是因 ,慢性创伤是动力 ,结节形成是果
OBJECTIVE: To analyze the CT features of lumbar intraosseous cartilaginous tubercle and to explore its cause and mechanism. Materials and Methods: Eleven cases of lumbar intraosseous cartilaginous tubercle were collected and scanned for the endplate plane of the lower vertebral body, the plane of the intervertebral disc and the plane of the upper edge of the inferior vertebral body. The lesion was found on the plane of the endplate or under Additional scanning 1 to 2 levels, the scanning layer thickness 2mm ~ 5mm. Results: CT findings of lumbar intraosseous cartilaginous nodules can be manifested as three types: Xu Mo’s nodules, tubercle type and nodular type. Conclusion: The lumbar intraosseous cartilaginous nodules occur in young and middle-aged adults. They are formed by the intervertebral disc nucleus herniation into the cancellous bone of the vertebral body. It is an independent disease. The birth defects are caused by chronic trauma and the nodules Formation is the result
