Abstract: 目的 分析软组织透明细胞肉瘤(CCSST)的临床、MRI和病理学表现.方法 回顾性分析5例经病理证实的CCSST的临床资料,并复习相关文献,观察其临床、MRI及病理学特点.结果 5例CCSST,肿瘤分别位于大腿、足部、肩部、肘部及腰背部.5例均接受MRI平扫及增强扫描,T1WI序列上,3例肿瘤信号稍高于肌肉信号,2例合并出血呈高低混杂信号;T2WI序列上,4例肿瘤均表现为高低混杂信号,1例肿瘤表现为均匀高信号;增强扫描4例不均匀强化,内见斑点状无强化出血区,1例明显均匀强化.3例区域淋巴结转移,1例肺转移,1例术后复发.结论 CCSST是一种罕见的恶性软组织肿瘤,好发于中青年四肢,MRI多表现为软组织深部混杂信号软组织肿块,常伴区域淋巴结转移,术后易复发,综合临床及MRI特点,对其诊断具有一定的意义.
