Broad ligament leiomyoma

Radswiki et al.

Broad ligament leiomyomas are leiomyomas that occur in relation to the broad ligament and are sometimes considered a variation in terms of location for a uterine leiomyoma.

While in most cases broad ligament leiomyomas are asymptomatic, patients may present pelvic pain or a palpable pelvic/abdominal mass. Pelvic pain may be as a result of pressure effects on adjacent organs or a complicating torsion.

It is a type of extra-uterine leiomyoma that arises from the broad ligament, often by a stalk.

A leiomyoma occurring in this location poses greater diagnostic difficulty than when it occur in the uterus. In uncomplicated cases (e.g no degeneration) it is seen as a solid adnexal mass which is separate from both the uterine body as well as the ovary.

Usually seen as an hypoechoic, solid, well-circumscribed adnexal mass, although that can be heterogeneous when large. There is generally no interface between tumour and uterus and no straight relation to the ipsilateral ovary.

Signal characteristics in uncomplicated cases are similar to those exhibited by uterine leiomyomas:

  • T1: iso to low signal
  • T2: typically low signal
  • T1 C+: most enhance similarly to the myometrium while larger leiomyomas tend to enhance less and heterogeneously

Torsion of the leiomyoma can occur if pedunculated.
