摘　　要：目的探讨子宫恶性苗勒氏管混合瘤(MMMT)的MR表现特点,提高对其认识。方法回顾性分析6例MMMT患者的临床资料及MR表现特征,所有病例均经手术病理证实。结果多数肿瘤体积较大,宫腔内肿瘤以膨胀性生长为主,伴局部肌层浸润。MR表现为信号混杂的囊实性肿块,可合并出血,肿瘤不均匀强化,较为典型的"蜂窝状"结构为其较为特征的MR征象。结论 MMMT有较为特征的MR影像表现,MR对其有较高的诊断价值。Objective To investigate the MR imaging features of malignant mullerian mixed tumor （MMMT） .Methods MR images and clinical data of 6 cases of histologically proven MMMT were reviewed and analyzed .Results Tumor volumes were large in most of MMMT .Expansive growth and local myometrial invasion were observed in intrauterine tumors .MR images showed heterogeneous solid-cystic masses ,which could complicate with hemorrhage and showed heterogeneous enhancement .Typical“honeycomb”structure was one characteristic sign on MRI .Conclusion MMMT shows some characteristic signs on MR imaging .MRI has preferable significance in the diagnosis of MMMT.
