Detection and management of pregnancy in rudimentary horn of uterus

Abstract

Pregnancy in rudimentary horn is extremely rare and usually terminates in rupture during first and second trimester of pregnancy. Diagnosis of rudimentary horn pregnancy and its rupture is difficult and can be missed in routine ultrasound scan; and in majority of cases, it is detected after rupture. It requires high index of suspicion. We present a case report of a woman who was misdiagnosed as having missed miscarriage; and termination was attempted, which ended up in failure and rupture of rudimentary horn was the consequence followed by laparotomy. With advances in prenatal ultrasound in recent decades, it is prudent to detect such a life-threatening condition earlier resulting in a lower incidence of maternal morbidity and mortality.
