Heterotopic ovarian pregnancy after clomiphene ovulation induction

Heterotopic pregnancy is a life threatening condition which seems to occur more frequently than previously estimated. We report a case of combined ovarian and intrauterine pregnancy after clomiphene treatment. Diagnosis was delayed because clinical presentation was atypical and ultrasound was falsely reassuring. The neonate was healthy but presented with a single umbilical artery. When an ectopic gestation is suspected after induction of ovulation or assisted reproductive technologies the presence of an intrauterine pregnancy can no longer be considered reassuring and an heterotopic pregnancy has to be ruled out.
