title: Expectant management of interstitial pregnancy.
abstract: A case of interstitial pregnancy is described. Transvaginal ultrasound examination, performed at 8 weeks' gestation, revealed an empty endometrial cavity with an eccentric gestational sac in the left uterine corner, with a clear separation between the uterine cavity (endometrium) and the gestational sac. Expectant management, consisting of repeated sonographic examinations and assessment of serum beta-human chorionic gonadotropin, resulted in a favorable outcome.
