Magnetic resonance imaging findings are reported for 12 pathologically proven lesions of clear cell carcinoma (CCC) of the ovary in 11 women (mean age 50 years). T1- and T2-weighted MR images were obtained in all patients, and gadolinium-enhanced MR images were obtained in 9. The mean diameter of the tumors was 13 cm. Seven patients presented with stage-I tumors. All 12 lesions consisted of cystic masses with solid protrusions occurring in 10 and solid masses in 2. The cysts were unilocular in 9 lesions and multilocular in 1. In four lesions, the cysts displayed with high intensity on T1-weighted images. Round solid protrusions were identified in 8 lesions. In 5 lesions, the number of protrusions was only a few. The solid portions of 5 masses had slightly high-intensity regions on T1-weighted images. The number of patients with ascites was three. Magnetic resonance imaging of CCC usually shows a unilocular large cyst with solid protrusions, which are often round and few in number. Such MR imaging findings suggest malignant tumor but are not specific.
