摘要
目的:探讨子宫癌肉瘤的MRI表现特点,提高其MRI诊断的正确率。方法:回顾性分析我院2017年1月至2017年12月经病理证实的7例子宫癌肉瘤患者的MRI表现。结果:子宫体积增大,宫腔内肿块。病灶体积较大(6例最大径大于5 cm),形态不规则,呈分叶状,边界不清晰。磁共振成像(MRI)特征:平扫T1WI呈等低或混杂信号,T2WI呈等、稍高混杂信号,部分合并出血。病灶实性部分DWI呈高信号,ADC图呈低信号,平均ADC值为(1.105±0.136)×10-3mm2/s。增强扫描不均匀强化,静脉期及延迟期持续强化,内部出血、囊变坏死区无强化。部分肿瘤侵犯宫颈,并向颈管内脱出。部分病灶合并盆腔和腹膜后淋巴结肿大。结论:病灶的大小形态、DWI高信号、较高的ADC值、早期及持续强化有助于子宫癌肉瘤的诊断及鉴别诊断,MRI对肿瘤浸润的深度和范围有较重要的意义。
Objective:To investigate the MRI features of uterine carcinosarcoma,to improve the accuracy of MRI diagnosis.Methods:The MRI findings of 7 cases of uterine carcinosarcoma confirmed by pathology from January2017 to December 2017 were analyzed retrospectively.Results:The volume of the uterus increases and the lumps in the uterine cavity increase.Larger size of lesion(6 cases with maximum diameter greater than 5 cm).Irregular form,in a leaf shape,the boundaries are not clear.MRI features:Flat sweep T1 WI is equal low or mixed signal,T2 WI is equal,slightly higher mixed signal,partial bleeding.The real part of the lesion DWI is high signal,the ADC diagram is low signal,the average ADC value is(1.105±0.136)×10-3 mm2.Enhanced scanning uneven enhancement,the venous phase and the delayed phase continue to strengthen,there was no enhancement of internal hemorrhage and cystic necrosis.Some tumors invade the cervix,and it is released into the neck tube.Part of the pelvic and retroperitoneal lymph nodes.Conclusion:Size and shape of the lesion,DWI high signal,higher ADC value,early and continuous strengthening,contribute to the diagnosis and differential diagnosis of uterine carcinosarcoma,MRI has a more important significance on the depth and extent of tumor invasion.
