Abstract

Herlyn-Werner-Wunderlich (HWW) syndrome is a rare congenital anomaly of the genitourinary tract comprising uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis. Patients with HWW syndrome usually present symptoms such as dysmenorrhea, abdominal pain, pelvic mass, and purulent vaginal discharge. If not treated at an appropriate time, complications such as infertility, endometriosis, pyosalpinx, and subsequent pelvic adhesions may occur. Here, we report a case of HWW syndrome in a 7-year-old-girl who was also diagnosed as having central precocious puberty. She was brought to the pediatric department with chief complaints of lump in her breast and vaginal discharge. When she was around 2 months old, she was confirmed to have a single kidney on ultrasonography. We checked her past medical history and diagnosed her as having HWW syndrome based on the results of imaging studies, including abdominal ultrasonography and pelvic magnetic resonance imaging. She underwent treatment with gonadotropin-releasing hormone analogue for 2 years. During 24 months of follow-up, she showed no serious problems or complications. If renal anomalies are identified immediately after birth or in infancy, further screening tests should be conducted prior to menstruation for determining congenital abnormalities of the reproductive tract and vice versa.
