This systematic review evaluated imaging features of adnexal lesions during pregnancy, analyzing 16 studies involving 1674 patients. The findings revealed that 93.1% of lesions were benign, with simple cysts being the most common. Diagnostic models like the IOTA strategy showed high specificity (70.0-90.2%) and negative predictive value (90.0-98.3%) for excluding malignancy, although misclassification of decidualized endometriomas as malignant was noted.
Key findings
- 93.1% of patients had benign lesions, while 3.4% had borderline ovarian tumors and 3.5% had malignant lesions.
- The most common benign lesions were simple cysts (39.0%), mature cystic teratomas (24.2%), and endometriomas (14.9%).
- BOTs were larger than decidualized endometriomas, with a median size of 88.0 mm vs 48.1 mm.
- IOTA models demonstrated high negative predictive value (90.0-98.3%) for excluding malignancy.
Why it matters
Understanding the imaging characteristics of adnexal lesions in pregnancy is crucial for accurate diagnosis and management. High negative predictive values of diagnostic models can aid clinicians in ruling out malignancy, thus influencing patient care and treatment decisions.
