| 目的 探讨卵巢透明细胞癌(OCCC)的MRI表现.方法 回顾性分析经手术病理证实为OCCC的12例患者资料.结果 12例均发生于单侧,多呈类圆形或圆形,边界清晰,肿瘤最大径8.5~20.0 cm.12例均为囊实性肿块,其中11例(11/12,91.67%)以囊性成分为主,囊腔内均可见形态不一的实性结节;1例(1/12,8.33%)以实性成分为主,且实性成分内见多发囊变.囊腔T1WI呈低信号9例(9/12,75.00%),等信号1例(1/12,8.33%),等高混杂信号1例(1/12,8.33%),高信号1例(1/12,8.33%);T2WI均呈高信号.实性成分T1WI均呈等信号,T2WI呈稍高信号,DWI呈高信号,动态增强扫描示实性成分动脉期不均匀强化,延迟期持续明显强化.结论 OCCC的MRI表现具有一定的特征性,有助于临床鉴别诊断. |

| Objective To explore the MRI manifestations of ovarian clear cell carcinoma (OCCC). Methods Datum of 12 OCCC patients confirmed by pathology were retrospectively analyzed. Results Tumors were unilateral in all patients. All the masses showed ovoid or round shape, smooth margin, and the maximum diameter ranged from 8.5 cm to 20.0 cm. The masses in 12 patients were all solid and cystic: Cystic-based masses were found in 11 patients (11/12, 91.67%), and multiple nodules were found in the cysts; solid-based mass was found in 1 case (1/12, 8.33%), and the mass was solid with cystic regions. The cyst cavity on T1WI showed hypointense in 9 cases (9/12, 75.00%), isointense in 1 case (1/12, 8.33%), isointense to hyperintense in 1 case (1/12, 8.33%), hyperintense in 1 case (1/12, 8.33%). The cyst cavity on T2WI all showed hyperintense. The signal of the solid parts all showed isointense signal on T1WI, hyperintense on T2WI, hyperintense on DWI, and heterogeneous enhancement in arterial phase, obvious enhancement in delayed phase. Conclusion MRI manifestations of OCCC have some characteristics, which are helpful in clinical differential diagnosis. |
