摘      要：BACKGROUND Collision tumor are neoplasms,including two histologically distinct tumors that coexist in the same mass without histological *** incidence of collision tumor is low and is rare *** To investigate ultrasound images and application of ovarian-adnexal reporting and data system(O-RADS)to evaluate the risk and pathological characteristics of ovarian collision *** This study retrospectively analyzed 17 cases of ovarian collision tumor diagnosed pathologically from January 2020 to December *** clinical features,ultrasound images and histopathological features were collected and *** O-RADS score was used for *** O-RADS score was determined by two senior doctors in the gynecological ultrasound *** with O-RADS score of 1-3 were classified as benign tumors,and lesions with O-RADS score of 4 or 5 were classified as malignant *** There were 17 collision tumors detected in 16 of 6274 patients who underwent gynecological *** average age of 17 women with ovarian collision tumor was 36.7 years(range 20-68 years),in whom,one occurred bilaterally and the rest occurred *** average tumor diameter was 10 cm,of which three were 2-5 cm,11 were 5-10 cm,and three were10 ***(29.4%)tumors with O-RADS score 3 were endometriotic cysts with fibroma/serous cystadenoma,and unilocular or multilocular cysts contained a small number of parenchymal ***(64.7%)tumors had an O-RADS score of 4,including two in category 4A,six in category 4B,and three in category 4C;all of which were multilocular cystic tumors with solid components or multiple papillary ***(5.9%)tumor had an O-RADS score of *** case was a solid mass,and a small amount of pelvic effusion was detected under *** pathology was high-grade serous cystic cancer combined with cystic mature *** were nine(52.9%)tumors with elevated serum carbohydrate antigen(CA)125 and two(11.8%)with
