Antenatal MR diagnosis of urinary hydrometrocolpos due to urogenital sinus

Abstract

Hydrometrocolpos is cystic dilatation of the vagina and uterus due to congenital vaginal obstruction. It may be secretory or urinary in character and manifests in the neonatal period with abdominal distension. Urinary hydrometrocolpos occurs in patients with urogenital sinus or cloacal anomaly. A rare case of antenatal MR diagnosis of urinary hydrometrocolpos due to urogenital sinus is presented.
