Abstract Objective: To improve the recongnition of CT and MRI in diagnosing ovarian clear cell carcinoma. Methods: The CT and MRI features in 25 ovarian clear cell carcinoma (OCCC) patients were analyzed. 17 patients underwent pre- and post-contrast CT scans, 8 patients underwent pre-and post-contrast MRI scans. Results: Unilateral mass was revealed in all 25 cases, which localized at the right side in 16 cases, left side in 9 cases. The maximum diameter of the mass ranged from 7.2 to 16.5 cm. The tumors appeared as the roundly well-defined mass in 21 cases, the lobulated mass in 4 cases, incomplete capsule in 2 cases. 18 cases appeared as a single cyst with single or multiple large solid nodules, namely “a single capsule with large nodule”. And the fibrous septa were found in 7 cases. The distribution of solid component had certain characteristics: Among the 25 cases, 18 cases were unilateral distribution (72%), which was located in the source side of the side wall in 5 cases, 8 cases in the posterior wall, 5 cases in the side wall, anterior and posterior walls; 2 cases of tumor located in the posterior wall, 5 cases of solid component was widely distributed. CT value of cystic part of the mass was 13-26 HU, while solid part was 31-52 HU. The cystic component showed heterogenous signal intensity on T1WI, high signal intensity on T2WI. The solid component showed low signal intensity on T1WI, slightly high signal intensity on T2WI, and restricted diffusion on DWI. On post-contrast CT and MRI images, the solid and septa component showed marked and delayed enhancement, while the cystic component showed no enhancement. 9 cases showed the enlarged ipsilateral ovarian arteriovenous and increased branches. Conclusion: CT and MRI appearance of OCCC can help improve the diagnostic ability of this rare disease.
