Unusual presentation of spontaneous heterotopic pregnancy: A case report

Abstract

Spontaneous heterotopic pregnancy is the natural co-existence of an intrauterine pregnancy with an ectopic pregnancy. It has a historic incidence of 1 in 30,000.  Its clinical presentations can be diverse and can challenge the diagnostic skills of clinicians. I present a case of spontaneous miscarriage of a 6 week intrauterine pregnancy in a patient with spontaneous heterotopic pregnancy. This presentation is an unusual clinical scenario for heterotopic pregnancy. To the best of my knowledge, there are no previous reports of such presentation in the literature. I highlight our diagnostic dilemma with this presentation and reiterate the essential tripod for diagnosis of heterotopic pregnancy.
