【摘要】：目的:探讨卵巢支持-间质细胞肿瘤(SLCT)的MRI表现,提高对此病的认识及诊断水平。方法:回顾性分析经手术及病理证实的8例卵巢SLCT的临床及MRI资料,观察肿瘤的部位、大小、形态、边界、囊实性、信号强度、强化程度、实性成分ADC值及伴发腹水、腹膜种植、淋巴转移等特征。结果:MRI上,8例患者共9个肿瘤(中分化7个,中低分化2个),1例患者术后半年对侧卵巢复发。肿块最大径4.4~21.7cm,平均11.2±6.8 cm。5个瘤呈囊性为主型,其中囊液呈均匀水样信号3个,信号不均匀2个;实性成分表现为囊壁及分隔的增厚或沿其生长的宽基底实质区瘤。另4个瘤呈实性,实性区在T2WI上呈低、等或稍高信号,其中2个瘤伴囊变。增强后实性成分明显强化8个,中度强化1个。DWI上,7例8个肿瘤实性成分均表现为DWI高信号、ADC图低信号;6个可测量肿瘤的实性成分平均ADC值为(1.028±0.273)×10~(-3) mm~2/s(0.717~1.381×10~(-3) mm~2/s),中低分化瘤的平均ADC值显著低于中分化瘤[(0.723±0.008)vs(1.181±0.176)×10~(-3) mm~2/s,P=0.025]。结论:MRI可显示卵巢支持-间质细胞肿瘤的形态学特征,结合DWI有助于判断其性质。
[Abstract]:Objective: to investigate the MRI findings of ovarian Sertoli stromal cell tumor (SLCT) and to improve the understanding and diagnosis of the disease. Methods: the clinical and MRI data of 8 cases of ovarian SLCT confirmed by operation and pathology were retrospectively analyzed. The location, size, morphology, boundary, cystic and solid, signal intensity, enhancement degree, ADC value of solid components and ascites were observed. Peritoneal implantation, lymphatic metastasis and other characteristics. Results there were 9 tumors (7 moderately differentiated and 1 moderately poorly differentiated) in 8 patients with upper gyrus on Mr imaging. The contralateral ovary recurred half a year after operation. The largest diameter of the tumor was 4.4 ~ 21.7 cm, with an average of 11.2 卤6. 8 cm.5, in which the cystic fluid showed homogeneous water signal (3) and heterogeneous signal (2). The solid components were cystic wall and thickened or broad basal parenchymal region. The other 4 tumors were solid, and the solid area was low, equal or slightly high signal intensity on T2WI, 2 of which were accompanied with cystic degeneration. After enhancement, 8 solid components were significantly enhanced. In 7 cases of moderate enhancement 1. DWI, 8 tumors showed high signal intensity and low signal intensity, and the average ADC value of 6 measurable tumors was 1.028 卤0.273 脳 10 ~ (-3) mm~2/s(0.717~1.381 脳 10 ~ (-3) mm ~ (-2) 路s ~ (-1). The average ADC value of middle and low differentiation tumor was significantly lower than that of moderately differentiated tumor [(0.723 卤0.176) 脳 10 ~ (-3) mm ~ 2 / s ~ (-1)]. Conclusion the morphological features of ovarian Sertoli-mesenchymal cell tumors can be demonstrated by Mr imaging, and combined with DWI can be helpful to judge the nature of ovarian Sertoli-interstitial tumors.
