Rudimentary Horn Pregnancy Misleading Abdominal Missed Abortion

Abstract

Pregnancy in a rudimentary horn is a very rare condition. It is responsible for severe complications and also a life threatening condition as it mostly terminates by rupture of pregnancy. This was a case of non communicating unruptered pregnancy which was misdiagnosed on 1st and 2nd transabdominal ultrasonography, progressing to 22weeks gestation and ends in a missed abortion. A transvaginal ultrasonography revealed it as an abdominal pregnancy and on laparotomy confirmed diagnosis was non communicating rudimentary horn pregnancy. Pregnancy sac with foetus was removed intact and patient. recovered without any complications. Gravid rudimentary horn may be misdiagnosed as abdominal pregnancy and are of interest in management.DOI: http://dx.doi.org/10.3329/jom.v15i1.19879 J Medicine 2014; 15: 74-76

Multimodality Study of a Twin Pregnancy Within a Rudimentary Horn

“…Mauriceau and Vassal first described rudimentary horn pregnancy in the literature in 1669. [1][2][3][4][5] In general, unicornuate uteri are rare, only making up about 5% of MDAs. 1,10 This uterine anomaly results from unilateral hypoplasia of the uterine ducts during fetal development.…”

“…9 Pregnancies within a rudimentary horn are uncommon. [1][2][3][4] It is estimated that about 600 to 700 pregnancies have been reported within the rudimentary horn at the time of this study. 1 Rupture of the rudimentary horn is considered a surgical emergency.…”

“…Pregnancy within a rudimentary horn is a rare occurrence. [1][2][3] It is about 1 in 76 000 to 1 in 140 000 of all pregnancies worldwide. [1][2][3][4][5] Uterine rupture is the most concerning complication associated with these pregnancies.…”
