Pre- and Postnatal Features of Hydrometrocolpos in One Fetus of a Dizygotic Twin Pregnancy

Abstract

A female fetus of a dizygotic pregnancy presented with a retrovesical cystic mass at 16 weeks. Severe and recurrent fetal ascitis developed at 25 weeks. Pre-eclampsia, probably due to mirror syndrome, precipitated fetal extraction, which led to severe prematurity complications and neonatal death. Necropsy showed: cloacal anomaly, anal atresia, ambiguous genitalia and bicornuate uterus.

“…Also, associated urinary and intestinal fistulae are usually present leading to urine and meconium being retained [8].…”

“…The mass in hydrometrocolpos arises secondary to vaginal outlet obstruction which results in retained vaginal and cervical secretions, that are secreted in response to circulating maternal estrogens [2]. Also, associated urinary and intestinal fistulae are usually present leading to urine and meconium being retained [8].…”
