Imaging Diagnosis of Herlyn-Werner-Wunderlich Syndrome-An Extremely Rare Urogenital Anomaly

Herlyn-Werner-Wunderlich (HWW) syndrome is a very rare congenital anomaly of the urogenital tract resulting from maldevelopment of both Mullerian and Wolffian ducts. It is characterized by the triad of uterus didelphys, obstructed hemivagina and ipsilateral renal agenesis. It generally presents at puberty shortly following menarche with the symptom of acute pelvic pain. Management of these cases is surgical and consists mainly of vaginoplasty with excision of the vaginal septum in order to release the obstruction and prevent the long term complication of recurrent pyocolpos and infertility. We report here a case of Herlyn-Werner-Wunderlich syndrome in a 13-year-old adolescent girl, emphasizing the role of imaging in the accurate and prompt diagnosis of this rare developmental urogenital anomaly. Only a few hundred such cases have been reported in literature till date.
