骨巨细胞瘤的影像学诊断探讨

Research of imaging diagnosis in giant-cell tumor of bone

目的:分析骨巨细胞瘤的X线平片、CT和MRI影像学表现,评价其诊断价值。方法:对52例经临床手术后病理学证实的骨巨细胞瘤病例的X线平片、CT和MRI影像学资料进行回顾性分析评估。结果:CampanacciX线分型和Jaffe病理分级分别为Ⅰ级10?15例,Ⅱ级28?25例,Ⅲ级14?12。结论:大多数骨巨细胞瘤依据X线表现可作出正确的诊断和鉴别诊断,CT和MRI能提供更多的信息提高鉴别诊断能力,对制订手术方案有重要意义。

Objective:To analyse the appearances and to evaluate the diagnostic value of X-ray,CT and MRI in giant-cell tumor of bone.Methods:Fifty-two cases of giant-cell tumor proved by pathology,their X-ray,CT and MRI were re-viewed.Results:According to Campanacci staging and Jaffe grading methods,10?15cases were categorized as stage?grade I,28?25as stage?grade II,14?12as stage?grade III.Conclusion:Most of the giant-cell tumors have typical X-ray appearances and there is no difficult in making a diagnosis and differential diagnosis.CT and MRI which supply more information for di-agnosis and the capability of differential diagnosis may be improved and may also play an important role in surgical planning.
