A Rare Case of Recurrent Non-Communicating Rudimentary Horn Pregnancy

Abstract

M Tiwari, B Subba, W Yoong and A Adewale

Introduction: A unicornuate uterus with a rudimentary horn is a uterine anomaly resulting from the incomplete development of one of the Müllerian ducts and an incomplete fusion with the contralateral side. Pregnancy in a rudimentary horn of the uterus is a rare clinical condition with a reported incidence of 1 in 100,000 to 140,000 pregnancies. It carries grave consequences for the mother and fetus as the diagnosis may be missed and subsequently result in an emergency due to spontaneous rupture of the enlarging rudimentary horn and massive intraabdominal bleeding. The standard treatment is the surgical excision of the rudimentary horn. The authors present a case of a rare recurrent rudimentary horn pregnancy that contained a viable pregnancy diagnosed in first trimester and managed with complete excision of the rudimentary horn along with the pregnancy in-situ.
