Uterosacral ligament

The uterosacral ligament is one of the supporting structures of the uterus. Uterosacral ligaments are not infrequently affected in cases of deep infiltrating endometriosis.

The paired uterosacral ligaments are extraperiotoneal structures which extend posteriorly from the uterine cervix to sacrum, providing the lateral boundaries of the rectouterine and rectovaginal space.

They are composed of smooth muscle and connective tissue along with splanchnic nerve fibers

  • anterior: lateral aspect of cervix and upper vaginal wall, torus uterinus
  • posterior: presacral soft tissues between S2 and S4, including coccygeus muscle, sacrospinous ligament, ischial spine, and presacral fascia ​2

Can be detected on CT as soft tissue density bands and on MRI as low T1 and T2 signal bands between the cervix and sacrum.
