Bridging Vessel Sign

Bridging vessel sign, also known as the bridging vascular sign, refers to the appearance of multiple vessels between the uterus and a pelvic mass adjacent to the uterus. The sign helps differentiate an exophytic uterine mass (e.g., a subserosal fibroid) from a pelvic mass adjacent to the uterus.

Color or power Doppler ultrasound show the vessels. On MRI, the vessels appear as curvilinear tortuous flow voids.
