Heterotopic pregnancy is a rare event that usually presents in the first 6-8 weeks of pregnancy.
A 35-year-old primigravida was referred to the hospital at 18+ weeks' gestational age for evaluation of chronic abdominal pain. Ultrasound revealed a heterotopic pregnancy. The patient underwent surgery for removal of the ectopic pregnancy.
Heterotopic pregnancy can present at any time during pregnancy and should be considered in any pregnant woman with abdominal pain.
