摘要
目的:分析卵巢甲状腺肿的CT与MRI特点。方法:对经手术病理证实的8例卵巢甲状腺肿患者影像学特点进行回顾性分析。结果:8例卵巢甲状腺肿中,发生在左侧附件2例,右侧附件6例。其中5例行全腹部CT平扫及增强检查,均表现为囊实性肿块,2例可见钙化;增强扫描囊壁、分隔及实性部分明显强化,囊性部分无强化;行全腹部MRI平扫及增强扫描3例,均为囊实性肿块,实性部分在T1WI、T2WI均呈等信号,不同的囊腔信号不同,2例可见T2WI极低信号,在T1WI上呈等高信号。增强扫描囊壁、分隔及实质部分强化明显,囊液未见明显强化。结论:CT上出现"高密度囊"和MRI出现T2WI极低信号,是卵巢甲状腺肿的特征性表现。
Objective：To analyze the characteristics of CT and MRI of struma ovarii. Methods：The imaging characteristics of 8 patients with pathologically proved struma ovarii were analyzed retrospectively. Results：Two cases were located in the left accessory and 6 cases were in the right. Plain CT and contrast CT were performed on 5 cases. All of the cases were cystic and solid;calcification was found in 2 cases. The solid component,cyst wall,interval of all cases were significantly enhanced;the cystic fluid showed no enhancement. Plain MRI and contrast MRI were performed on 3 cases;all were cystic and solid. The solid components were intermediate intensity on both T2-weighted images and T1-weighted images. The signal intensity of different cysts was various. The areas of prominent low intensity on T2-weighted images were recognized in 2 cases,which were intermediate or high intensity on T1-weighted images. The solid component,cyst wall,interval of all cases were significantly enhanced;cystic fluid showed no enhancement.Conclusion：The prominent low intensity on T2-weighted images on MRI and the high density cyst＇on CT are the characteristic expressions of struma ovarii.
