Sonographic diagnosis of advanced ectopic pregnancy. A case report

The diagnosis of advanced extrauterine pregnancy is made most often sonographically by identification of a uterus separate from the fetus. Leiomyomas or other pelvic masses can make the sonographic diagnosis more difficult. In a woman with an advanced ectopic pregnancy and uterine leiomyoma, the sonographic diagnosis was made by passing a sterile probe through the endocervix with simultaneous, real-time ultrasound observation.
