EP02.11: Longitudinal ultrasound morphology and radiomic features of decidualized endometriomas and borderline ovarian tumors in pregnancy

examinations were reviewed by an experienced gynecological sonologist who was blinded of the cases.Results: There were a total of 57 patients diagnosed with metastatic ovarian tumor.Bilaterality was seen in 35% of cases, with a total of 77 ovarian lesions included in the analysis.The majority of the cases presented as unilateral solid tumors with heterogeneous echopattern, without acoustic shadowing.Ovarian metastases from breast cancer tend to be more often solid and less than 10 cm.Tumors from primary lung carcinoma present as hyperechogenic solid tumors with small cystic spaces and ''sponge''-like appearance.The ''lead vessel'' was appreciated across all organs except for the colon-appendix-bile duct group.Associated ascites was not a common finding in cases of metastatic ovarian tumors.Conclusions: The results of this study demonstrated sonographic findings of metastatic ovarian tumors that may contribute to preoperative differentiation and identification of the primary tumor.
