摘　　要：目的探讨骨盆巨大单发性骨软骨瘤的X线征象及其诊断价值.方法对经病理及临床综合确诊的7例骨盆骨软骨瘤的X线表现及CT表现进行回顾性分析,发生于髂骨3例、耻骨2例、坐骨1例及股骨颈1例.结果表现为骨盆骨菜花状骨性突起,基底与骨盆骨相连,边界清楚,肿块内见骨皮质及小梁与骨盆骨相延续,其内可见钙化;恶变表现为软骨帽钙化模糊、密度变淡或中断,伴骨质破坏及软组织肿块形成.结论骨盆单发性骨软骨瘤的X线表现具有一定特征性,结合临床具有较高诊断价值.Objectives To improve the diagnosis rate of the pelvis giant solitary osteochondroma through the discussion of X-ray sign and diagnosis value.Methods We retrospectively analyzed the X-ray signs and CT expression of 7 cases pelvis solitary osteochondroma which already be identified by pathological mechanism and clinical diagnosis.Among the 7 cases,the tumor of 3 cases in ilium;2 cases in pubis;1 case in ischium;and 1 case in neck of femur.Results This disease had the following signs: pelvic bone cauliflower-like bony prominences,basement and the pelvic bone were joined,frontier was clear,inside the tumor the cortical bone,trabecula continued with pelvic bone,and the calcification also was find.The malignant change presented that the cartilage caps calcification was not clear,and the density became thin or was broken off,and was accompanied with the bonedestruction and soft tissue tumor formed.Conclusion The X-ray image of Pelvis Giant Solitary Osteochondroma has certain characteristics,and has high diagnosis value when combined with the clinical diagnosis.
