目的：分析20例软骨母细胞瘤的影像学表现，对比X线片、C T以及M RI图像上的差异，分析其与病理的关系。方法对20例经手术病理证实的软骨母细胞瘤的影像学及病理资料进行回顾性分析，对同一影像表现在不同影像学图像上的征象差异进行对照研究。结果发生在长骨骨端的病变共17例，12例有膨胀性与窗格样改变，10例中心性生长，10例偏心性生长。病灶边界清楚，13有硬化边，11例累及关节面，4例位于关节面以远，17例破坏区内有钙化灶，5例有关节腔积液，5例有骨髓水肿，1例伴软组织肿块。结论软骨母细胞瘤有特征性影像学表现，并且与病理学有一定的关系，了解这些有助于提高本病的诊断符合率。

Objective To assess the role of radiography ,computed tomography and magnetic resonance imaging in the a‐nalysis of 20 patients with chondroblastoma ,and to analyze its pathologic basis .Methods The imaging results were retro‐spectively analyzed in 20 patients with chondroblastoma confirmed by pathology ,and compared with pathological section . Results 17 cases located at epiphysis of long bone .Expanding and window‐like changes were found 12 cases ,centric growth in 10 cases ,and eccentric in 10 .All the lesions presented with clearly visible edge ,13 lesions showed sclerotic rim ,11 leisons involved the articular surface ,and 4 were abarticular .Calcification was found in 11 lesions ,articular cavity hydrops in 5 ,bone marrow edema in 2 .Only one showed soft tissue mass .Conclusion The imaging appearances of chon‐droblastoma has some characteristics ,and is related to its pathologic basis and understanding this is helpful to improve the diagnosis coincidence rate .
