Ultrasound showing a heterotopic pregnancy (intrauterine + extrauterine pregnancies) with signs that the extrauterine (ectopic) pregnancy has ruptured.[1]

Obstetrics
A heterotopic pregnancy is a complication of pregnancy in which both extrauterine (ectopic) pregnancy and intrauterine pregnancy occur simultaneously.[2] It may also be referred to as a combined ectopic pregnancy, multiple‑sited pregnancy, or coincident pregnancy.
The most common site of the extrauterine pregnancy is the fallopian tube. However, other sites of implantation include the cervix, ovary, and abdomen.[3]
Although heterotopic pregnancies were once thought to be a rare phenomenon, the incidence has increased due to the increasing use of assisted reproductive technologies.[3]
