Abstract

A cornual pregnancy occurs when the conceptus implants at the cornus of the uterus which is the junction between the fallopian tube and uterine cavity. Cornual pregnancy is a rare form of ectopic pregnancy and its diagnosis is difficult. It accounts for 2 to 4% of tubal pregnancy and rupture usually occurs between 8 weeks and 16 weeks of gestation. The rich vascularity in this location makes the rupture particularly dangerous, resulting in higher maternal mortality. We have experienced a case of unruptured cornual pregnancy at 9 weeks of atypical ultrasonographic findings, which was hourglass appearance. We present this case with a brief review of the literature.
