Idiopathic Recurrent Polyhydramnios: A Rare Case Report

Polyhydramnios occurs in 1-2% of pregnancies and may be idiopathic in more than half of the cases. The diagnosis of idiopathic polyhydramnios can be made only in the absence of maternal diabetes, fetal anomalies, aneuploidies, multiple gestation, Rh incompatibility, placental tumours and non-immune hydrops. Rarely, idiopathic polyhydramnios may be recurrent in future pregnancies and sometimes neonatal examination may reveal cause of polyhydramnios. Preterm delivery and associated fetal anomalies are the main concerns with recurrent polyhydramnios. Very few cases of recurrent idiopathic polyhydramnios have been reported in literature with a maximum number of four pregnancies being affected consecutively. We report here a case of idiopathic polyhydramnios which recurred consecutively in three pregnancies with a good neonatal outcome.
