Typically, clinicians think of ectopic pregnancies as occurring outside of the uterus. This case is important in underscoring the fact that there are variants of ectopic pregnancies that exist within the uterus. One classic type is the cornual ectopic pregnancy, which occurs in a congenital bicornate uterus. The shape of this uterus may allow for implantation to occur high in one of the cornual limbs.
