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. 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. The presented case was unique in that the pregnancy was believed to be a normal intrauterine pregnancy till 24 week's of gestation, when it ruptured and presented as the pregnant patient with hypovolemic shock of unknown cause. We present this case with a brief review of the literature.

Key Words: Cornual pregnancy, Second trimester pregnancy, Uterine rupture
