X线、CT、MRI在骨巨细胞瘤诊断中的应用价值

X-ray,CT and MRI in the Diagnosis of Giant Cell Tumor of Bone

目的分析骨巨细胞瘤的X线、CT和MRI表现形式,进一步探讨骨巨细胞瘤的临床影像学表现。方法方便选取该院自2004年1月—2014年12月经病理证实的78例骨巨细胞瘤病例,对其的临床表现、临床症状、X线、CT和MRI的表现进行研究分析。结果发生于长管状骨骨端56例,其余22例为骨盆、脊柱及不规则骨,病灶呈偏心性囊肿膨胀性骨破坏,界限清楚锐利,有骨脊但无分隔,无钙化,富血供;MRI表现为病灶边缘清楚,T1WI为等、低信号,T2WI为不均匀高信号,CT增强及Gd-DTPA增强扫描肿瘤实体呈中度到明显强化。结论在临床骨巨细胞瘤诊断中,通过较为系统、仔细的分析骨巨细胞瘤的X线、CT和MRI表现,从而能为骨巨细胞瘤提供更多的诊断依据。

Objective To analyze the giant cell tumor of X-ray, CT and MRI manifestation, further to explore the clinical imaging findings of giant cell tumor of bone. Methods Convenient collected from January 2004 to December 2014 pathologically proven cases of 78 cases of giant cell tumor, analyzed the clinical manifestation, clinical symptoms, X-ray, CT and MRI. Results The lesions of 56 cases patients located in end of long bone. The remaining 22 cases occurred in the pelvis,spine and irregular bone. Expansion of lesions were eccentric cyst bone destruction, clear sharp boundaries, separated by a crest but no, no calcification, the rich blood supply MRI lesions show clear edge, T1 WI was so low signall, T2 WI high signal for the uneven,Enhanced CT and Gd-DTPA enhanced MRI showed a tumor entity moderate to marked enhancement,12 cases liquid-liquid surface. Conclusion In clinical diagnosis of giant cell tumor of bone, giant cell tumors of bone through a systematic and careful analysis of the X-ray, CT and MRI manifestations, which provide more diagnostic basis for giant cell tumor of bone.
