Background: Communicating double uterine anomalies are defined as mullerian defects which involve two hemiuteri with communication between the uterine halves. Nine subcategories of communicating uterine anomalies have been described; only two of these subcategories are associated with hemivaginal obstruction. Case: An 11-year-old white female was brought to the Emergency Department with fever and acute pelvic pain. This condition was found to be caused by abscess formation behind an obstructed left hemivagina with involvement of a communicating double uterine anomaly. Conclusion: To our knowledge, this is the first case report involving a communicating double uterine anomaly in which fever was a presenting symptom.

Background: Women with communicating double uterine anomalies are at increased risk for obstetric complications, including early pregnancy loss, preterm delivery, and breech presentation. We present the pregnancy of a woman with a previously diagnosed communicating double uterine anomaly. Case: An 18-yr-old white female with a previous diagnosis at age 11 of a communicating double uterus, double cervix, and obstructed left hemivagina was followed during the course of her pregnancy. She experienced no complications until 36 6/7 weeks, when she was found to have signs and symptoms of mild preeclampsia. The fetus was in a breech presentation and a cesarean section was performed. Two hemiuteri were identified intraoperatively. The communication was not visualized. A viable male infant was delivered without complications. Conclusion: This patient represents only the sixth report of successful pregnancy in a woman with a Toaff type 5A communicating uterine anomaly.
