目的探讨骨巨细胞瘤(giant cell tumor of bone,GCT)的X线平片、CT影像学表现,评价其诊断价值。方法对12例经临床手术病理证实的GCT病例的X线平片、CT影像学资料进行分析。12例均行常规X线检查,其中5例行CT检查。结果 12例中8例病变发生于长管状骨,7例长管状骨病灶位于骨性关节面下方。11例呈膨胀性生长,7例为偏心性,2例单房性溶骨性破坏。结论常规X线片有着良好的空间分辨率,是诊断GCT重要和首选的检查方法,CT能提供更多的信息,用来提高诊断和鉴别诊断能力。
Objective To investigate the X-ray plain film and CT imaging features of giant cell tumor of bone (GCT) and evaluate its diagnostic value. Methods X-ray plain film and CT imaging data of 12 cases of GCT confirmed by clinical pathology were analyzed. All 12 cases underwent routine X-ray examination, and 5 of them underwent CT examination. Results Eight lesions occurred in long tubular bone in 12 cases, and 7 long tubular bone lesions were located below the bony joint surface. 11 cases showed expansive growth, 7 cases had eccentricity, and 2 cases had single-body osteolytic destruction. Conclusion Conventional X-ray films have good spatial resolution and are an important and preferred method for diagnosing GCT. CT can provide more information to improve diagnostic and differential diagnostic capabilities.
