Unusual presentation of heterotopic pregnancy

Abstract

Heterotopic pregnancy is a rare occurrence in naturally conceived pregnancy and is difficult to assess as pain and bleeding may be due to abortion. We report a case of spontaneous heterotopic pregnancy which was missed in initial transabdominal scan and was reported to be intrauterine pregnancy and was later identified as heterotopic pregnancy with serial beta-human chorionic gonadotropin levels and clinical features. If assisted reproductive treatment procedures are not involved, it is likely to be missed and may lead to serious and delayed consequences.
