摘要 目的 评价脊柱骨巨细胞瘤MRI诊断价值.方法 回顾性分析9例经手术病理证实的脊柱骨巨细胞瘤患者的临床资料和MRI表现.结果 9例脊柱骨巨细胞瘤中发生于胸椎2例,腰椎3例,骶骨4例,所有病例均累及椎体和附件,7例累及单个椎体,1例累4个椎体,1例累及2个椎体;其中2例术后复发.MRI 检查,其中4例可见明显肿块,5例椎体呈不同程度压缩性改变,5例可见多个小囊样改变;除1例因病灶内出血T1WI 序列呈高低混杂信号外,其余8例T1WI 序列为等、低信号, T2WI序列呈不均匀高信号,Gd-DTPA增强后,病灶呈不均匀中度到明显强化.结论 MRI能提供比较全面的影像学信息,对脊柱骨巨细胞瘤具有很高的诊断及鉴别诊断价值. Objective To evaluate the MRI diagnostic and differential diagnosis of giant cell tumor of spine. Methods The clinic data and MRI findings of 9 cases with giant cell tumor of spine proved by operation and pathology were analyzed retrospectively. Results In the 9 cases,2 cases were originated from thoracic column, 3 were originated from lumbar column and 4 originated from sacral vertebra.All the 9 cases were located in corpus vertebral and appendix.Only 1 vertebral column was involved in 7 cases,2 adjacent vertebral columns were involved in 1 case,and 4 adjacent vertebral columns were involved in 1 case.2 cases recurred after surgery.In the MR images, 4 cases showed obvious mass,5 cases showed compression fracture of the involved vertebrae, and 5cases showed cystic changes within the mass.Only one tumor was demonstrated high signal intensity on TI weighted images because of hemorrhage,the others were all demonstrated low to intermediate signal intensity on TI weighted images and heterogeneously high signal intensity on T2 weighted images.All lesions were depicted as heterogeneously moderate or obvious enhancement after gadolinium administration. Conclusion MRI could provide much more comprehensive imaging information and has significant diagnostic and differential diagnosis value of giant cell tumor of the spine.
