骨巨细胞瘤的X线诊断及病理分析

Radiodiagnosis and pathological analysis of osteoclastoma

目的:对骨巨细胞瘤的X线诊断及病理进行探讨和分析。方法:收集我院28例骨巨细胞瘤患者,对其X线征象进行分析。结果:28例骨巨细胞瘤中,25例位于长管状骨,2例发生在髂骨,1例发生在骶骨;均为单发。19例为偏心性膨胀性骨质缺损,可见数量不等的骨性分隔或皂泡样改变,6例可见钙化,5例表现为溶骨性破坏,4例骨质破坏区见软组织肿块。病理分级:28例中,Ⅰ级16例,Ⅰ～Ⅱ级8例,Ⅲ级4例。结论:骨巨细胞瘤的X线表现具有一定的特征性,但诊断必须结合临床、X线、CT、MRI和病理。骨巨细胞瘤的影像学表现与病理分级无明显相关性。

Objective： To explore and analyze X-ray diagnosis and pathology of osteoclastoma. Methods： 28 cases of patients suffered from osteoclastoma were selected in our hospital, and their X-ray findings were analyzed. Results： Among all cases, 25 cases occurred in long tubular bone, 2 cases occurred in the ilium, and 1 case in the sacrum. Each was single. 19 cases had eccentric and expansive bone defects, ossiform separation or soap bubble-like changes could be seen. 6 cases had calcification. 5 cases showed osteolytic destruction. 4 cases showed soft tissue tumor in the bone destruction zone. Pathological grade： 16 cases in Ⅰ class, 8 cases in Ⅰ - Ⅱ class, 4 cases in Ⅲ class. Conclusion： X-ray manifestations of osteoclastoma have certain characteristics, but the diagnosis must be combined with clinical, X-ray, CT, MRI and pathology. Imaging manifestations of osteoclastoma and its pathologic grading have no significant correlation.
