摘要: 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。Abstract: 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.
