Abstract

Objectives: the study aimed to evaluate the value of magnetic resonance imaging (MRI) for distinguishing ovarian clear cell carcinoma (CCC) from high–grade serous carcinoma (HGSC). Methods: we analyzed MRI data of 34 tumors in 30 patients with CCC, were compared with those of 49 tumors in 32 patients with HGSC, comfirmed by surgery and pathology. MRI features included: laterality, shape, size, configuration, papillary projection, signal intensity, enhancement, peritoneal implant, lymphadenopathy, ascites. Results: there was a statistically significant difference in the mean maximum diameter, laterality (p < 0.001 and p = 0.001, respectively) between CCC and HGSC. Compared to HGSCs, CCCs were more frequently oval (26/34, 76.5% vs 9/49, 18.4%; p < 0.001), more often cystic (19/34, 55.9% vs 7/49, 14.3%; p < 0.001) and unilocular (20/26, 76.9% vs 5/23, 21.7%; p <0.001), had T1-hyperintense cystic components more often (16/26, 61.5% vs  4/23, 17.4%; p = 0.002), had larger papillary projections (53.3 ± 19.5mm vs 23.8 ± 12mm; p < 0.001), were peritoneally implanted less frequently (p = 0.09) and had fewer ascites (p < 0.001). Conclusion: CCC typically showed an oval, unilocular cystic mass with large papillary projection and T1-hyperintense cystic components. MRI could be helpful for distinguishing CCC from HGSC.
