The transvaginal component allows for detailed evaluation with the transabdominal component helpful for larger lesions that may be suboptimally seen transvaginally. US Pelvis Transvaginal The most useful modality for evaluation of adnexal masses includes transvaginal US combined with a transabdominal US approach. Variant 2: Adult patient assigned female at birth. Adnexal mass, likely benign, no acute symptoms. Premenopausal. Follow-up imaging. CT Pelvis With IV Contrast CT pelvis with IV contrast is usually not useful to follow likely or known benign adnexal masses. Because the roles of US and MRI are well established, there is little reason presently to obtain a CT for benign mass follow-up. CT Pelvis Without and With IV Contrast CT pelvis without and with IV contrast is usually not useful to follow likely or known benign adnexal masses. Because the roles of US and MRI are well established, there is little reason presently to obtain a CT for benign mass follow-up. CT Pelvis Without IV Contrast CT pelvis without IV contrast is usually not useful to follow likely or known benign adnexal masses. Because the roles of US and MRI are well established, there is little reason presently to obtain a CT for benign mass follow-up. Clinically Suspected Adnexal Mass FDG-PET/CT Skull Base to Mid-Thigh There is no role for the use of FDG-PET/CT in the follow-up of benign adnexal masses in premenopausal patients. MRI Pelvis Without and With IV Contrast Although MRI can accurately characterize these benign lesions, it is not the first-line modality [16,17]. If a known lesion requiring surveillance is unable to be followed via US, MRI would be the alternative imaging modality of choice for follow-up. Classically benign lesions such as simple cysts, endometriomas and dermoid, and extraovarian benign lesions have characteristic appearances on MRI and can be confidently diagnosed as almost certainly benign [17].
