Abstract：Objective To analyze the clinical characteristics of ovarian tumors during pregnancy and explore the diagnostic value of MRI examination in patients with ovarian tumors during pregnancy.Methods This retrospective study analyzed MRI findings and clinical data from 67 pregnant patients diagnosed with ovarian tumors during pregnancy confirmed by postoperative histopathology.Results A total of 82 ovarian tumors were identified in 67 patients,with 15 cases exhibiting bilateral involvement.Tumor diameters ranged from 2.0-34.7(9.3±4.9)cm.Histopathological subtypes included:11 mature cystic teratomas,11 mucinous cystadenomas,10 serous cystadenomas,9 endometriotic cysts,7 luteinized cysts,6 corpus luteum cysts,3 simple cysts,4 borderline tumors,3 high-grade serous carcinomas,1 sex cord-stromal tumor,1 dysgerminoma,and 1 metastatic tumor.MRI demonstrated a diagnostic accuracy of 91.5%,with 7 cases misdiagnosed.Most ovarian tumors appeared as cystic or cystic-solid masses.Benign tumors predominantly presented as cystic lesions,whereas borderline and malignant tumors tended to show solid components.No statistically significant differences were observed between benign,borderline,and malignant tumor groups regarding tumor size,presence of pedicle torsion,or elevation of tumor markers(P>0.05).In terms of clinical management and outcomes:7 patients underwent pregnancy termination during the first trimester due to absence of fetal heart tones or lower abdominal pain;22 patients with benign tumors underwent surgery during the second trimester,primarily via laparoscopy,due to abdominal pain or large tumor size;30 patients with benign or borderline tumors were monitored via ultrasound and underwent tumor resection during term cesarean section.Among 6 patients with malignant tumors,1 terminated the pregnancy due to fetal chromosomal abnormalities,2 experienced preterm delivery following fetal lung maturation and subsequently underwent radical surgery,and 3 underwent fertility-sparing surgery during the second trimester.Overall,maternal and fetal outcomes were favorable.Conclusion Ovarian tumors during pregnancy are predominantly benign and asymptomatic.MRI is a valuable tool for the qualitative assessment of these tumors,supporting accurate diagnosis and informed clinical decision-making.
