摘　　要：目的:探讨MRI扫描对卵巢卵泡膜细胞瘤(OT)的诊断价值。方法:回顾性分析经手术确诊18例卵泡膜细胞瘤病例的MRI表现及与病理和相关实验室检查的关系。结果:患者平均年龄51.3±7.29岁,18位患者,21个肿瘤灶,其中单侧15例,双侧3例,9例病灶合并囊变,16例盆腔积液,14例Ca125≥35U/ml,肿瘤平均大小6.54±2.58cm。MRI扫描T1WI呈等、略低信号,T2WI呈高低混杂信号,囊变部分呈高信号,DWI序列b800呈显著高信号,相应ADC呈低信号,增强扫描病灶因卵泡膜细胞含量不同,有不同程度强化。结论:卵泡膜细胞瘤(OT)在MRI上有其特征性的表现和强化方式,结合相关实验室检查,可以在术前做出较为准确的诊断。Objective： to explore the diagnostic value of MRI scan on Ovarianthecoma（OT）. Methods： the MRI findings of 18 cases of Ovarian Thecoma and the relationship between pathology and laboratory examination were retrospectively analyzed. Results： in patients with an average age of 51. 3 ± 7. 29 years old,18 patients,21 tumors,including 15 cases of unilateral,3 cases of bilateral,9 cases were combined with cystic changes,16 cases of pelvic effusion and 14 cases of Ca125 were greater than 35 U/ml. Mean tumor size 6. 54 ± 2. 58 cm. MRI scans T1 WIslightly low signal,T2 WI with mixed signals,sac become part of a high signal,DWI b800 was significantly high signal,ADC is low signal. because of theca cells content is different,have different degree of reinforcement. Conclusion： Ovarian Thecoma（OT） has its characteristic manifestation and enhancement mode on MRI,combined with relevant laboratory examination,it can make a more accurate diagnosis before surgery.
