Simultaneous intra- and extrauterine pregnancy after multiple ovulation induction.

Superovulation was induced by combined treatment with a GnRH analog, hMG and hCG in a 31 years old nulligravida with a diagnosis of unexplained infertility. She developed a mild hyperstimulation syndrome for which she received conservative treatment in hospital, and she was discharged only after we demonstrated a gestation sac in utero with evident fetal heart beat and beta hCG assays were positive. One week later the patient was readmitted urgently with acute abdominal pain. Laparoscopy revealed a left tubal pregnancy with corpus luteum on the right ovary and free blood in the pouch of Douglas. Salpingotomy was therefore performed with dilatation and curettage of the uterine cavity. Histological examination confirmed the presence of contemporary intra- and extrauterine pregnancy. Based on this first communication, a high index of clinical suspicion for an extrauterine pregnancy is warranted in all patients undergoing superovulation even after a pregnancy in utero has been demonstrated.
