Hydro-metro-colpos diagnosed in utero

Abstract

Hydro (metro)colpos (H(M)C) should be suspected in any female foetus with a pelvic fluid mass. This malformation has a very variable spectrum from a simple imperforate hymen, a persistent urovaginal sinus, or to a cloacal malformation. It can be isolated or syndromic. An accurate prenatal diagnosis allows to orientate the management according to the severity of the anatomical malformation. We present prenatal management and evolution of two cases of hydrocolpos that are at both extremes of this complex malformation, and that were diagnosed with antenatal imaging (foetal ultrasound and MRI): a hydrocolpos secondary to an imperforate hymen and a severe cloacal anomaly.
