title: Preeclampsia due to fetal non-immune hydrops: mirror syndrome and review of literature.
abstract: OBJECTIVE
  Mirror syndrome (Ballantyne's syndrome) refers to the association of fetal hydrops and maternal preeclampsia. The aim of this study was to determine the relation and incidence between fetal hydrops and preeclampsia in our clinic.
  
  
  METHODS
  A retrospective review of patients associated with fetal hydrops and findings with preeclampsia was used. Seventy-five cases with single pregnancy and diagnoses with nonimmune hydrops fetalis were found. According to the data 4 cases were found related with preeclampsia.
  
  
  RESULTS
  Mirror syndrome is rarely encountered and underdiagnosed. We found a frequency of 5.3% (4 cases in 75 affected pregnancies) for single non-immune hydrops cases in which maternal hypertension occurred. Fetal outcome is depending on etiology and prognosis is mainly very low. Maternal symptoms and laboratory findings are resolving after intrauterine fetal death or delivery.
  
  
  CONCLUSIONS
  Hydrops fetalis must be considered as a potential risk factor for preeclampsia. It is important that this clinical condition has a potential of about 5% for proceeding preeclampsia.
