Subserosal leiomyoma of the uterus

Subserosal 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 .

Clinical presentation

They are usually asymptomatic although some pedunculated subserosal leiomyomas may undergo torsion, which results in infarction accompanied by pain .

Radiographic features

On imaging, they can be identified either as sessile or pedunculated para uterine mass. Subserosal leiomyomas may demonstrate the bridging vessel sign on MRI, which represents flow voids in feeding branches of the uterine arteries .

Please refer to the main article on uterine leiomyomas for a detailed discussion on their other imaging features.
