An atypical Müllerian duct anomaly: Duplicated cervices and vaginas with a single uterine cavity.

Müllerian duct anomalies include a wide variety of developmental abnormalities involving the female reproductive system, many of which are not adequately represented by the current classification system used in the United States. Diagnosis can be made with imaging, but initial evaluation first requires a thorough physical exam. A 19-year-old female received a pelvic MRI for evaluation of a Müllerian duct anomaly following an abnormal pelvic exam. Imaging demonstrated a single uterine cavity which divides into 2 distinct cervices and vaginas. The patient received a hysteroscopic resection of her vaginal septum. This type of anomaly is extremely rare and associated clinical outcomes of potential infertility or complications with vaginal delivery are uncertain. Use of a more comprehensive classification system for Müllerian duct anomalies may assist with identification and research of such rare subtypes.
