Rudimentary horn pregnancy

Abstract

Rudimentary horn is an anatomic variant of unicornuate uterus which is a mullerian duct anomaly resulting from the incomplete fusion of the ducts. The prevalence of congenital uterine malformations is about 3.2%Pregnancy in the rudimentary horn is an extremely rare condition occurring in 1 in 76,000 to 1 in 1,40,000 pregnancies. Unicornuate uterus with rudimentary horn maybe associated with gynecological and obstetric complications like infertility, endometriosis, hematometra, abortions and preterm deliveries. Despite advances in ultrasound and other diagnostic modalities, prenatal diagnosis remains elusive, with confirmatory diagnosis being laparotomy.
