Myometrial cysts

Myometrium cysts are cysts seen in the myometrium and these can be differentiated appropriately based on location and sonological or Doppler features.


  1. adenomyosis: the cysts are most often seen in the endomyometrial junction region. They ideally are small <5 mm, however may be large. As it is a basic ectopic functioning endometrial gland, the cysts may be thick walled, have internal debris, or fluid fluid levels.
  2. arcuate veins: not really cysts but these cystic structures are classically seen in the outer third of the uterus and on Doppler would demonstrate a flow
  3. nabothian cysts in cervix: these are relatively common and are classically seen in the region of cervix.
  4. post-Caesarean cyst: seen in the lower uterine segment in the anterior aspect, near the cesarean scar. It most often will be associated with the wedge shaped defect in the endometrium.
