title: Cogan syndrome in pregnancy.
abstract: BACKGROUND
  Cogan syndrome is a rare, multisystem, autoimmune disorder of unknown etiology. Little is known about whether it affects pregnancy or whether pregnancy affects the disease.
  
  
  METHODS
  A 24-year-old primigravid woman with Cogan syndrome diagnosed 3 years before her pregnancy presented to our clinic for prenatal care. During pregnancy she experienced no worsening of symptoms of her disease but reported subjective improvement in vision and hearing. Cesarean delivery was performed at term because of nonreassuring fetal status. There were no obstetric or postpartum complications.
  
  
  CONCLUSIONS
  Cogan syndrome requires close monitoring. If it worsens, then the disease process can be similar to both physiologic and pathologic changes of pregnancy. However, unlike the former, worsening Cogan syndrome can have irreversible maternal consequences.
