An interesting case of Herlyn-Werner-Wunderlich syndrome.

Herlyn-Werner-Wunderlich syndrome (HWWS) is a rare congenital anomaly characterized by uterus didelphys with blind hemivagina and ipsilateral renal agenesis. Usually, such patients present with dysmenorrhea shortly after menarche, increasing pelvic pain and a palpable mass due to the obstructed hemivagina. Interestingly in the present case, the patient had her menarche seven years ago, but dysmenorrhea started only 1-year back. She never sought medical help previously as she was mostly asymptomatic all through the years. It was only after she conceived and got investigated for antenatal concerns that she was found to have HWWS. A tortuous history and an unusual clinical presentation made this case an interesting one.
