title: A heterotopic pregnancy involving a caesarean section scar.
abstract: Heterotopic pregnancy refers to the presence of simultaneous pregnancies in two different implantation sites, generally one intra-uterine pregnancy and one extra-uterine pregnancy (usually tubal). This is a rare case of a heterotopic pregnancy involving concurrent intra-uterine pregnancy and caesarean section scar pregnancy (CSEP). CSEPs are at a high risk of bleeding and uterine rupture, carrying with them significant maternal morbidity.
