摘　　要：目的:探讨卵巢硬化性间质瘤(OSST)的MR表现特点,提高对该疾病影像诊断正确率,减少误诊漏诊。方法:回顾性分析13例经我院手术病理证实的卵巢硬化性间质瘤MR影像表现。结果:13例均为单发,左侧7例,右侧6例。10例囊实性、3例实性。实性者信号均匀。囊实性病例中8例实性成分为主者,呈等-稍长T1等-长T2信号;2例以囊性为主,实质部分呈等T2、囊性部分呈长T2信号,内壁见结节样影,局部“梳齿”样改变。本组13个病例增强动脉期均见病灶外周呈斑片状、结节状或梳齿状强化,静脉期、延迟期肿瘤实性部分渐进性、向心性强化。结论:卵巢硬化性间质瘤MRI强化形式颇具特征性,结合临床相关资料,可提高对此病的正确诊断率。Objective:To investigate the MR findings of Ovarian Sclerosing Stromal Tumor,and to improve the correct diagnosis rate of the disease.Methods:The MRI manifestations of 13 patients with OSST who were proved pathologically in our hospital were analyzed retrospectively.Results:All of the 13 patients were solitary with seven left sided cases and six rightsided cases.Tumors were divided into second types:solid 3 cases,cystic solid 10 cases.There was 3 case of solid mass with uniform signal.The signal of tumors in 8cases whose most component issolid were mixed with TI WI of low and equal signal and T2WI of high.Two cases of tumor showed equal signal in T2 WI,and the cystic part showed long T2 signal.Node and papillae could be seen in its inner wall with the shape of"comb"locally.MRI enhancement scanning showed the edge of tumor had obviously enhancement with the nodular,or comb-like enhancement.in the arterial phase,and the solid part of the tumor had progressive and centripetal enhancement in the venous and the delayed phase.Conclusion:The MRI enhancement pattern of the OSST has considerable characteristic which can enhance the rate of a correct diagnosis of that disease when combined with relevant clinical information.
