An unusual case of ruptured noncommunicating rudimentary horn pregnancy at 10 weeks

ABSTRACT

Unicornuate uterus with noncommunicating rudimentary horn occurs due to incomplete fusion of mullerian ducts. Pregnancy in this horn is a rare phenomenon usually resulting in rupture during second trimester of pregnancy. Prerupture diagnosis of pregnancy in rudimentary horn with ultrasonography is technically difficult, with sensitivity of 30%. We report a case of ruptured non-communicating rudimentary horn at 10 weeks 3 days in a woman. She had a routine USG before pregnancy in which diagnosis was missed. Later she presented to emergency in shock, with massive hemoperitoneum and ruptured horn. So, a high index of suspicion is required to save this catastrophic event and associated maternal morbidity and mortality.
