Myometrial cysts

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



They can arise from variable etiology and include.

  • 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.
  • 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
  • nabothian cysts in cervix; these are relatively common and are classically seen in the region of cervix.
  • post-Cesarean 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.
  • cystic degeneration of a leiomyoma
