摘　　要：目的 探讨透明细胞软骨肉瘤(CCCS)CT、磁共振成像(MRI)表现。方法 回顾性分析2018年5月至2021年5月86例本院接收的疑似CCCS患者的资料。将患者术前CT、MRI检查结果 与术后病理结果 进行比较,分析CT、MRI对CCCS的诊断价值。结果 86例疑似CCCS患者的病理结果 ,共有77例CCCS,CT、MRI检查结果 发现CT误诊9例,漏诊6例,诊断符合率为82.56%(71/86),MRI检查误诊5例,漏诊1例,诊断符合率为90.70%(78/86)两种检测方法 的诊断符合率比较,差异无统计学意义(P=0.117)。分析77例CCCS患者CT和MRI征象,发现MRI检查肿块内坏死、分隔强化的征象阳性率分别为100.00%和90.91%,显著高于CT检查的81.82%和68.83%(P<0.05);MRI检查钙化征象阳性率为15.58%,显著低于CT检查的79.22%,差异均有统计学意义(P<0.05)。结论 CT、MRI检查中,CCCS有一定的特异征象,CT检查对钙化灶检出率较高,MRI检查对肿块内坏死、分隔强化的检出率较高,二者对CCCS的诊断符合率较高。Objective To explore CT and magnetic resonance imaging(MRI) manifestations of clear cell chondrosarcoma(CCCS).Methods A retrospective analysis was performed on the data of 86 patients with suspected CCCS admitted to the hospital between May 2018 and May 2021.The preoperative examination results of CT and MRI were compared with postoperative pathological results.The diagnostic value of CT and MRI in CCCS was analyzed.Results A retrospective analysis was performed on the pathological results of 86 patients with suspected CCCS,and there were 77 cases confirmed with CCCS.It was found by the retrospective analysis on the examination results of CT and MRI that there were 9 misdiagnosis cases and 6 cases missing diagnosis by CT,and its diagnosis coincidence rate was 82.56%(71/86).There were 5 misdiagnosis cases and 1 case missing diagnosis by MRI,and its diagnosis coincidence rate was 90.70%(78/86).There was no significant difference in diagnosis coincidence rate between the two methods(P=0.117).By analyzing CT and MRI signs in the 77 CCCS cases,it was found that the positive rates of lumps necrosis and sepa ration enhancement by MRI were100.00% and 90.91%,significantly higher than those by CT(81.82%,68.83%)(P<0.05).The positive rate of calcification signs by MRI was significantly lower than that by CT(15.58% vs 79.22%)(P<0.05).Conclusion In CT and MRI examinations,there are certain specific signs in CCCS.The detection rate of calcification lesions is relatively higher by CT,while detection rates of lumps necrosis and separation enhancement are relatively higher by MRI.The diagnostic coincidence rate of the two methods is relatively higher for CCCS.
