【摘要】 目的探讨脊椎骨巨细胞瘤的MRI表现。方法回顾性分析9例经穿刺或手术病理证实的脊椎骨巨细胞瘤的MRI表现。结果发生于颈椎2例,胸椎3例,腰骶椎4例,共累及13个椎体,除2例椎体呈破坏塌陷改变外,其余椎体呈不同程度的膨胀性破坏,T1WI呈等、低信号,T2WI常呈混杂信号,呈低、中等或高信号,增强扫描呈不同程度均匀强化。结论MRI对脊柱骨巨细胞瘤有很高的诊断价值。更多还原

【Abstract】 Objective To investigate the MRI manifestations of spinal giant cell tumor.Methods Nine cases with pathologically proved spinal giant cell tumor were enrolled and the MRI findings were retrospectively studied.Results The lesions were located at cervical vertebras in 2 cases, at thoracic vertebras in 3 and at lumbosacral spine in 4. In total 13 vertebrae were affected. Vertebral compression was seen in two cases, while expansive bone destruction at vertebrae was seen in 7 cases. The tumors manifested hypo-to intermediate intensity of signal on T1-weighted images and miscellaneous signal on T2-weighted MR images. Homogenous enhancement was revealed at the lesions. Conclusion MRI is a valuable imaging modality in the diagnosis of spinal giant cell tumor.更多还原
