[Vaginal ultrasound scanning causing misdiagnosis of a pregnant patient with hormonal induction of ovulation].

We present the case of a 21-year-old woman who developed a simultaneous extra- and intrauterine pregnancy after hormonal induction of ovulation. The case shows a delay in the detection, relying on usual measures as vaginal ultrasound scanning, of the ectopic pregnancy resulting in peritonealia and an acute laparoscopy. This is a reminder of the increase in the prevalence of heterotopic pregnancies as a result of hormonal induction of ovulation, and indicates that laparoscopy is the gold standard of detecting the cause of abdominal pain including ectopic pregnancy.
