title: Hyperreactio luteinalis in a normal singleton pregnancy. A case report.
abstract: BACKGROUND
  Hyperreactio luteinalis rarely occurs in normal singleton pregnancy. About 50 such cases have been published. This case is noteworthy because it resulted in extremely enlarged ovaries and was accompanied by a hyperandrogenic state and high level of human chorionic gonadotropin.
  
  
  METHODS
  A gravida was referred to our department because of large, bilateral, cystic ovaries diagnosed by ultrasonography in the 28th week of gestation. Markedly elevated levels of androgens and human chorionic gonadotropin were noted. During the following six weeks the ovarian masses enlarged, and the hyperandrogenic state worsened. Cesarean section and, because of a bleeding right adnexectomy, left ovarian resection were performed. Histology confirmed the presumed diagnosis of hyperreactio luteinalis. The placenta was unremarkable. Seventeen weeks after surgery the hormone levels were normal.
  
  
  CONCLUSIONS
  Our case suggests the possibility that in certain cases of hyperreactio luteinalis, an idiopathic elevation of human chorionic gonadotropin, can occur even in normal singleton pregnancies. Furthermore, it calls attention to the necessity of ultrasonographic demonstration of ovaries even during late pregnancy.
