Sub-serosal uterine leiomyoma is a subtype of uterine leiomyoma that often exophytically projects outwards from a subserosal location. While its exact definition may vary, a leiomyoma is often called subserosal if >50% of the fibroid protrudes out of the serosal surface of the uterus 2. They can be either sessile or pedunculated.
Clinical presentation
They are usually asymptomatic although some pedunculated subserosal leiomyomas may undergo torsion, which results in infarction accompanied by pain 1.
Radiographic features
MRI
Sub-serosalSubserosal leiomyomas may demonstrate the bridging vessel sign, which represents flow voids in feeding branches of the uterine arteries3.
