Herlyn-Werner-Wunderlich Syndrome: Comparison of Two Cases.

Lower abdominal pain accompanying hematocolpos suggested Herlyn-Werner-Wunderlich Syndrome (HWWS) as the cause of symptoms. 3D transvaginal ultrasound enabled the determination of a congenital uterine defect with high probability, although inconclusive cases required confirmation by laparoscopy. Incision of the blocked vagina and drainage of hematocolpos were the key components of treatment. The treatment of HWWS is a multi-step process.
