摘要
笔者分析了60例不同部位椎体软骨结节的CT、MRI表现。典型表现：（1）CT表现椎体上下缘终板内的类圆形、三角形或分叶状骨质缺损，边缘致密硬化，（2）MRI表现为在T1WI及T2WI上与相连髓核等信号结节，结节周围表现为长T1短T2低信号环，几乎与椎体皮质相等；（3）发生于椎后缘的软骨结节常合并不同程度的椎管和／或侧隐窝狭窄，也可促使椎间盘的突出而中重椎管和／或倒隐窝狭窄的程度。根据自家经验，并结合文献，笔者指出椎体软骨结节多形成于青少年时期，是由椎间盘组织破裂的椎体终板突入椎体松质骨而形成的。
CT and MRL findings of 60 cases of vertebral intraosseous nodes in different lo-cations were analyxed. The results showed (1) that the typical CT findings were a marginal defect and a marginal sclerosis of the affected vertebral body; (2) the typical MRI findings were the T1WI or T2 WI signal intensity of the intraosseous node were the same with that of nucleus pulposus; and the area around the node was a low intensity signal circle with long T1and shortT2; (3) the intraosseous node in the vertebrae pos- terior margin or the intervertebral disc her-niation caused by the node may lead to spinal stenosis. According to the study and reviewing literature, authors conclude that vertebral intraosseous node may result from herniating of intervetebral disc material into the bone of vertebral through a ruptured vertebral end-plate during adolescence.
