Abstract
Background
We present a rare case of a dichorionic-diamniotic twin pregnancy in a noncommunicating rudimentary uterine horn diagnosed prior to rupture at 12 weeks of gestation.
Case
A 33-year-old woman with history of two prior spontaneous abortions presented with a spontaneously conceived dichorionic-diamniotic twin pregnancy. Routine first-trimester screening ultrasound detected an extrauterine twin pregnancy. The patient was admitted for observation and treatment planning. Magnetic resonance imaging (MRI) of the pelvis led to the radiologic diagnosis of suspected abdominal ectopic pregnancy. Exploratory laparotomy led to an intraoperative diagnosis of twin pregnancy within a rudimentary uterine horn, which was removed without incident.
Conclusion
This is a rare case of a twin pregnancy contained in a noncommunicating rudimentary uterine horn. The presence of this horn was not detected on ultrasonography or MRI.
Ectopic twin pregnancy found within noncommunicating rudimentary horn not seen on ultrasound or magnetic resonance imaging
Noncommunicating rudimentary uterine horns can be missed on imaging.
Ectopic pregnancy in a noncommunicating uterine horn can appear as an abdominal ectopic pregnancy.
Early detection of Mullerian anomaly in pregnancy is potentially lifesaving.
Selective preoperative imaging can guide patient counseling and ensure necessary consulting services are available.
