Double cervix and vagina with a normal uterus and blind cervical pouch: a rare müllerian anomaly.

OBJECTIVE: To report a rare müllerian anomaly with a blind cervical pouch.
DESIGN: Case report.
SETTING: Private practice and community hospital. PATIENT(S): A 27-year-old nulliparous patient referred for evaluation of suspected müllerian anomaly. INTERVENTION(S): Clinical and outpatient surgical evaluation of the anomaly. MAIN OUTCOME MEASURE(S): Assessment of the anomaly according to standard müllerian classification system and subsequent literature search. RESULT(S): A rare müllerian anomaly was found that did not fit within the standard classification system, which included a double cervix and vagina with a normal uterus and blind cervical pouch. This was found to have been described only once before after extensive review of the literature. CONCLUSION(S): The described anomaly is extremely rare, with no prior cases reported in the United States. The described anomalies in this case report are inconsistent with the generally accepted understanding of müllerian development and do not fit into the current classification system.
