少见部位骨巨细胞瘤的X线影像分析

目的统计分析一组少见部位骨巨细胞瘤的Ｘ线影像表现,对易与之混淆的４种骨病提出鉴别诊断,以加深认识。方法搜集经手术、病理证实的少见部位骨巨细胞瘤４８例Ｘ线平片、ＣＴ和动脉造影片资料进行回顾性分析。结果表现为囊状膨胀性骨质破坏３０例,且内多有肥皂泡沫状表现;溶骨性骨质破坏１０例;骨外有软组织肿块,骨塌陷变扁伴局部膨出４例;侵犯邻骨４例;骨质增生硬化３例;异常血管及“肿瘤染色”３例。结论Ｘ线平片对少见部位骨巨细胞瘤诊断具有重要价值,ＣＴ优于平片,动脉造影有助于诊断与制定治疗方案。

Analysis of X-ray images of giant-cell tumor of bone of rare locations

Objective To analyse X ray images of giant cell tumor of rare locations. Methods To retrospectively review the X ray films, CT scans and arteriograms of 48 cases of surgically and /or pathologically confirmed giant cell tumor of bone of rare locations. Results Of the 48 cases, expansive cystic destructive changes of the bone with soap bubble like appearence was found in 30 cases, osteolytic destruction in 10 cases, soft tissue mass outside of bone with sinking, flattening and local expanding of bone in 4 cases, invading into neighboring bone in 4 cases, hyperplasia and sclerosis of bone in 3 cases and staining of abnormal blood vessels and tumors in 3 cases. Conclusion For the diagnosis of giant cell tumor of bone of rare locations, X ray plain film is of great value. CT is even better than plain film; arteriogram is helpful for diagnosis and treatment planning.
