目标。本文对10例脊柱巨细胞瘤的MRI表现进行了分析。其中一个肿瘤位于C7。其余9例肿瘤位于胸椎、腰椎和骶骨，各3例。特征性表现为肿块肿大，t2加权像呈不均匀低至中等信号强度（10/10），T1和t2加权像呈曲线状信号空洞区（9/10），肿块内囊性改变（4/10）。虽然没有影像学特征是典型的，但MRI在识别肿瘤，揭示其范围以及确定其与椎管内结构的关系方面是有价值的。
OBJECTIVE. The purpose of this article is to describe the MRI features of giant cell tumors of the spine in 10 patients.CONCLUSION. One of the tumors was located in C7. The other nine tumors were located in the thoracic spine, lumbar spine, and sacrum, three in each site. The characteristic findings included an expansile mass with heterogeneous low to intermediate signal intensity on the T2-weighted images (10/10), a curvilinear area of signal void on T1- and T2-weighted images (9/10), and cystic changes within the mass (4/10). Although no imaging feature was pathognomonic, MRI was found to be valuable in identifying the tumor, revealing its extent, and defining its relationship with the intraspinal structures.
