title: Eclampsia complicating hydatidiform molar pregnancy with a coexisting, viable fetus. A case report.
abstract: BACKGROUND
  Eclampsia is a rare and serious complication of pregnancy. The occurrence of preeclampsia prior to the 20th week of gestation has been associated with concurrent hydatidiform molar pregnancy. We present a case of eclampsia complicating a partial molar pregnancy associated with a viable fetus.
  
  
  METHODS
  A 22-year-old white woman, gravida 1, para 0, at 14 weeks' gestation, presented with an excruciating headache associated with hypertension, proteinuria and a viable intrauterine fetus with gastroschisis. Subsequently the patient had a generalized tonic-clonic seizure which resolved with magnesium sulfate therapy. Markedly elevated quantitative human chorionic gonadotropin and a moderately thickened placenta were the sole clinical features suggestive of a molar gestation. Dilation and evacuation was performed revealing unremarkable products of conception. Pathologic and cytogenetic analyses revealed a triploid fetus (69,XXX) consistent with partial molar pregnancy.
  
  
  CONCLUSIONS
  Development of preeclampsia/eclampsia prior to 20 weeks of gestation should prompt a clinical evaluation to exclude the possibility of an underlying hydatidiform molar pregnancy.
