摘　　要：目的探讨骨巨细胞瘤的X线平片、CT、MRI影像学表现。方法回顾分析经手术病理证实17例骨巨细胞瘤的影像学表现。结果 10例发生于长骨骨端(胫骨上端3例、股骨下端7例),以偏心性、膨胀性骨质破坏为主,周围无明显骨质硬化,内无钙化;7例发生于脊柱(颈椎1例、胸椎2例、骶椎4例),以膨胀性骨质破坏为主,发生于骶椎者,多位于骶椎1～2水平(2例位于骶1,2例位于骶2)。结论 X线平片结合CT、MRI能显著提高骨巨细胞瘤诊断准确率,对临床制定手术方案有重要意义。Objective To analyze the imaging appearances of X-ray, CT, and MRI in giant cell tumor of bone （GCT）. Methods The imaging features were retrospectively analyzed in 17 cases of giant cell tumor of bone proved by operation and pathology. Results 10 cases located in the top of long bone in which 3 cases located in the top of the tibia and 7 cases located in the bottom of the tibia. The common radiographic features were eccentric, expanded bony destruction, no obvi ous sclerosis in peripheral and calcification in near area. 7 cases located in the spine （1 case of cervical vertebra, 2 cases of thoracic vertebra, 4 cases of sacral vertebra） had the radiographic features of expanded bony destruction. The lesion loca- ted in sacral vertebra distributed upper part, commonly in S1-2 （2 cases of S1 , 2 cases of Sz ）. Conclusion Imaging exami nations, including X-ray, CT and MRI, can show well the tumor and the peripheral structures and improve the diagnosis. Besides above, imaging examinations can also help to facilitate surgical planning.
