Herlyn-Werner-Wunderlich Syndrome Consisting of Uterine Didelphys, Obstructed Hemivagina and Ipsilateral Renal Agenesis in a Newborn

Abstract

Herlyn-Werner-Wunderlich (HWW) syndrome is a rare variant of Müllerian duct anomalies consisting of uterine didelphys, obstructed hemivagina, and ipsilateral renal agenesis. Patients with HWW syndrome are usually asymptomatic until menarche, when they present with acute lower abdominal pain. Here we report a case of a female newborn with right renal agenesis diagnosed during the pregnancy. The patient presented with a protruding mass over the vaginal introitus that was associated with an obstructed hemivagina and uterine didelphys.
