Establishing a meaningful differential diagnosis during the sonographic evaluation of an adnexal mass requires the determination of the organ of origin. The authors presents two cases of pedunculated fibroids with uncharacteristic ultrasound findings, in which they demonstrate a clear vascular pedicle between each mass and the uterine fundus by color-flow Doppler sonogtaphy. The "vascular pedicle sign" may be a valuable sonographic tool for those cases in which defining the organ of origin of an adnexal mass is difficult.

Key Words: adnexal mass • color-flow Doppler • subserosal fibroids • ultrasound diagnosis
