目的:探讨X线平片、CT及MRI对非典型部位骨巨细胞瘤的诊断价值.方法:回顾性分析19例经手术病理证实的非典型部位的骨巨细胞瘤的X线平片、CT及MRI表现.其中,19例行X线平片检查,19例行CT检查,16例行MRI检查.结果:骶椎9例,坐骨4例,跖骨2例,掌骨、腕骨、肩胛骨,腰椎各1例.X线平片及CT表现:膨胀性、溶骨性骨质破坏区,无硬化边;MRI表现:病灶在T1WI常呈等-低信号,T2WI呈不均匀高信号.结论:运用多种影像检查方法,可提高对非典型部位骨巨细胞瘤的认识,做出准确的诊断.

Objective:To analyze imaging of giant cell tumor of bone in atypical Locations on plain film, CT and MRI. Methods:Nineteen cases with histologically confirmed giant cell tumor of bone in atypical Locations were reviewed. Radiography was performed in 19 cases, CT in 19 cases and MRI in 16 cases. Results:giant cell tumor of bone located at sacral in 9 cases, at ischial in 4 cases, at metatarsal in 2 cases, metacarpal, wrist, shoulder blades, lumbar each one case. Expanding growth and osteolytic destruction were on X–ray or CT, without hardened edge. MRI show low to intermediate signal on T1WI, hyperintensity on T2WI. Conclusion: Use of various imaging methods can improve the understanding of giant cell tumor of bone in atypical Locations, to make an accurate diagnosis.
