Herlyn-Werner-Wunderlich syndrome with pregnancy: a rare presentation.

Müllerian duct anomalies are infrequently encountered clinical problems and often present with difficulty in diagnosis. A high level of suspicion is the key to diagnosis, which is usually made soon after menarche. However, this is the first reported case of uterus didelphys with obstructed hemivagina and pyocolpos with ipsilateral renal agenesis in which the diagnosis was delayed until pregnancy.
