AB Key  PointsThe  cause  of  fetal  ovarian  cysts  is  unclear  but  is  most  likely  due  to  stimulation  of  the  fetal  ovaries  by  fetal  gonadotropins,  maternal  estrogens,  and  placental  chorionic  gonadotropin.Fetal  ovarian  cysts  are  most  often  unilateral  but  there  have  been  reported  cases  that  are  bilateral.Two  types  of  cysts  have  been  described:  simple  cysts  and  complicated  cysts.The  antenatal  natural  history  is  variable  with  some  cysts  resolving,  some  becoming  complex,  most  likely  due  to  torsion,  and  some  remaining  stable.Fetal  intervention  (cyst  aspiration)  is  controversial  but  should  be  considered  when  the  cyst  is  simple  in  nature  and  greater  than  4  cm  in  diameter.Delivery  should  occur  in  a  center  with  appropriate  pediatric  surgical  expertise  available.After  delivery,  the  neonate  should  have  an  ultrasound  to  confirm  the  diagnosis.Many  simple  cysts  will  resolve  in  the  neonatal  period.  Surgery  should  be  considered  for  complex  cysts.
