目的探讨跗骨成软骨细胞瘤的影像表现.方法回顾分析经病理证实的134例成软骨细胞瘤的部位分布情况,对其中11例跗骨成软骨细胞瘤的X线和5例CT表现进行分析.结果 11例跗骨成软骨细胞瘤患者中,病变位于距骨6例、跟骨3例、足舟骨2例.距骨体后部及跟骨后结节为好发部位,X线表现以膨胀性骨质破坏为主(10/11),局部边缘轻度硬化(11/11),骨嵴常见(9/11),关节面破坏常见(7/11),可见斑点状钙化(6/11);CT对关节面破坏(5/5)、小的骨嵴(5/5)以及细小钙化(2/5)的显示更明显.结论距骨、跟骨是跗骨成软骨细胞瘤好发部位,影像表现具有一定特点,但应结合其发病部位与其他疾病鉴别.

Objective To analysis the imaging features of the chondroblastoma in the tarsal bone. Methods The locations of 134 cases of pathologically confirmed chondroblastoma were retrospectively analyzed. Eleven of them were in tarsal bones and their X-ray and CT findings were analyzed. Results Of the 11 cases of tarsal chondroblastoma, 6 were in talus, 3 were in calcaneus and 2 cases were in navicular bones. They were examined by the X-ray and 5 cases had additional CT scans. The common locations were the posterior portion of the talus and calcaneus. The X-ray findings included expansive destruction (10/11), mild osteosclerosis (11/11), bone ridge (9/11), articular facet destruction (7/11) and spot or patching calcification(6/11). The imaging findings of CT included articular facets destruction (5/5), bone ridge (5/5) and spot or patching calcification (2/5). Conclusion The talus and the calcaneus are the frequently involved location of tarsal chondroblastoma. Its X-ray and CT findings are characteristic but not exclusive.
