【摘要】：目的:探讨卵巢内膜样腺癌(OEC)的MRI表现,提高对该病的认识。方法:回顾性分析经手术和病理证实的20例OEC的MRI表现,观察肿瘤的部位、形态、大小、肿块质地、壁结节、信号强度、强化程度、腹膜种植灶、腹水、同时伴发子宫内膜癌的双原发癌(DPC)、子宫内膜息肉、子宫内膜异位症及临床分期等情况。结果:20例OEC共22个病灶,单侧发病18例(90%),双侧2例(10%),DPC 10例(50%)。13个(59%)病灶呈卵圆形,最大径约(11.2±5.1)cm(3.7~22.5cm)。病灶呈囊性为主伴壁结节15个(68%),囊实性病灶5个(23%),实性病灶2个(9%)。囊液T1WI呈均匀等或高信号者17例(85%),T2WI呈均匀高信号者15例(75%),DWI呈低信号者10例(63%,10/16)。实性成分T1WI均呈等信号,19个(86%,19/22)病灶T2WI呈不均匀高信号,14个(82%,14/17)病灶DWI呈高信号。出现卵圆形病灶、囊性为主伴壁结节、囊液T1WI呈均匀等或高信号时,诊断OEC的准确率分别为59%、68%和85%,联合上述3种征象诊断OEC的准确率为91%。结论:OEC的MRI表现有一定特征性,结合DWI有助于OEC的诊断。
[Abstract]:Objective: to investigate the MRI features of ovarian intima-like adenocarcinoma (OECs) and to improve the understanding of the disease. Methods: the MRI findings of 20 cases of OEC proved by surgery and pathology were retrospectively analyzed, and the location, shape, size, mass texture, wall nodule of the tumor were observed. Signal intensity, degree of enhancement, peritoneal implant focus, ascites, double primary carcinoma with endometrial carcinoma, endometrial polyp, endometriosis and clinical stage were analyzed. Results 22 lesions were found in 20 cases of OEC. The lesions were oval in 18 cases with unilateral disease, 10 cases with DPC and 10 cases with DPC on both sides. The maximum diameter was about 11.2 卤5.1 cm ~ (-1) cm ~ (-1) ~ 3.7m ~ 22.5 cm ~ (-1). The lesions were mainly cystic with wall nodules (15 / 68), cystic solid lesions (5 / 23) and solid lesions (2 / 9). In 17 cases with homogeneous or high signal intensity on T _ 1WI, there were 15 cases with hypointensity on 75 / 75 / T _ 2WI and 10 / 10 / 16 / 16 with hypointensity on 75 / 75 / T _ 1 / T _ 2WI. On T1WI, 19 lesions showed homogeneous hyperintensity on T2WI, 14 lesions showed high signal intensity on DWI, and oval lesions appeared oval lesions. The diagnostic accuracy of OEC was 59 68% and 85% respectively when cystic fluid presented homogeneous or high signal intensity on T1WI. The accuracy rate of diagnosis of OEC combined with the above three signs was 91. Conclusion the MRI manifestations of OEC in the case of OEC have some characteristics, and the combination of DWI is helpful to the diagnosis of OEC.
