title: Simple adnexal cysts in postmenopausal women: conservative management.
abstract: OBJECTIVE
  To evaluate the expectant management of asymptomatic small, anechoic, simple ovarian cysts diagnosed by echography in postmenopausal women. To gain insight in the natural history of these cysts.
  
  
  METHODS
  Thirty six postmenopausal women with asymptomatic ovarian cysts (from 1.5 to 5.0 cm) diagnosed by ultrasonography and with a CA 125 serum level within the normal range and a non-suspicious color Doppler were followed conservatively. Visits were scheduled at 8-10 weeks of the diagnosis, at 6-month intervals twice and annually thereafter.
  
  
  RESULTS
  The follow-up period extended from 4 to 70 months with an average of 31.5 months. There were no cases of cyst enlargement. The cysts remained unchanged in 29 cases (80.5%), decreased in size in four cases (11.1%) and disappeared in three cases (8.3%).
  
  
  CONCLUSIONS
  We think that the possibility of malignant transformation of one of these cysts is remote and the benefits of conservative management greatly outweighs its risks.
