摘　　要：目的比较骨囊肿与内生软骨瘤的临床和影像学特征。方法对1990-2006年收集的资料完整并经手术病理证实的单发内生软骨瘤(15例)、骨囊肿(40例)的临床与计算机X线摄影(CR)平片资料进行回顾性分析。结果骨囊肿CR平片表现为骨髓腔中心性椭圆形或圆形透亮区,周围边界清晰,有薄层硬化骨质;骨皮质不同程度膨胀变薄,无骨膜反应;合并骨折时可见典型的"骨片陷落征"。内生软骨瘤CR平片表现为囊样类圆形透光区,瘤内钙化,呈膨胀性生长骨皮质变薄。结论影像学检查对此两种病大多数可做出定性与鉴别诊断。Objective To compare the clinic and imaging features of simple bone cyst and solitary enchondroma. Methods Computed radiography（CR） were performed in the cases of bone cyst and solitary enchondroma confirmed by pathology. The imaging findings were retrospectively analyzed in our hospitals from 1990 to 2006 year. Results Bone cyst X-ray showed bone marrow cavity central oval or circular translucent area around the border clear, and thin bone sclerosis;Cortical thinning expansion to varying degrees, and no periosteal reaction;When the merger fracture typical ＂fallen fragment sign＂. Plain radiography showed typical radiographic features including a well defined central lucency in the diaphysis of the metacarpal bones of fingers with calcifications inside the lesions and lobulated contour the cottex was thinned and cortical expansion also might occur. Conclusion The qualitative and differential diagnosis of simple bone cyst and solitary enchondroma could be made mostly by imaging examination.
