摘　　要：目的:探讨卵巢甲状腺肿的MRI特征性表现及主要鉴别诊断,提高对本病的认识。方法:回顾性分析经手术病理证实的卵巢甲状腺肿11例,总结其部位、病变形态、信号特征、囊壁及间隔强化方式的诊断价值。结果:11例卵巢甲状腺肿发生于右侧附件区3例;左侧附件区8例;囊性有间隔,囊壁及间隔较厚8例;完全囊性,囊壁较厚2例;囊实性混杂1例;增强扫描实性成分、囊壁及分隔明显强化,囊内未见强化;其中5例盆腔少量积液,3例盆腔积液合并双侧胸腔积液。结论:卵巢甲状腺肿MRI表现具有一定的特征性。MRI检查是诊断卵巢甲状腺肿有价值的方法。Objective：To observe MRI features and differential diagnosis of struma ovarii（SO） and to enhance the cognition of this disease Methods：11 patients with pathologically confirmed SO were analyzed retrospectively,and the topogenesis,morphology,sign,and schedule of cyst wall and interval reinforcement of all cases were summarized. Results：3 tumors were located in right accessory and 8 cases in left.Of the 11 cases,8 exhibited cyst with interval and thick cystic wall,2 appeared simple cyst with thick cystic wall,and 1 showed solid with cystic lesion.Solid component,cyst wall,and interval were markedly enhanced after administration of contrast medium.5 presented with little fluid in pelvic cavity,and 3 with fluid in pelvic cavity accompanied by bilateral pleural effusion. Conclusion：The MRI appearances of SO have a certain characteristic,which represents a valuable method in the diagnosis of SO.
