Abstract
A unicornate uterus with a rudimentary horn is a rare Müllerian duct abnormality. This uterine anomaly may cause variable gynecologic complications, including hematometra, endometriosis leading to acute pelvic pain, infertility, and obstetric complications, including miscarriage, preterm delivery, and rupture of the uterus, especially when the pregnancy implants in the rudimentary horn. To date, the standard treatment for the latter condition has been laparotomy, as patients usually experience massive abdominal hemorrhage or pregnancies too large to attempt laparoscopic removal. We report a case of a non-communicating rudimentary uterine horn pregnancy which was preoperatively diagnosed by ultrasonography, hysterofiberscopy, and magnetic resonance imaging, and then subsequently resected laparoscopically.
