Commentary: Three-dimensional transvaginal ultrasound diagnosis of interstitial ectopic pregnancy in a unicornuate uterus: A case report

Abstract

A rare case of unicornuate uterus with interstitial ectopic pregnancy (IEP) was diagnosed using three-dimensional transvaginal ultrasound (3D-TVUS). The ultrasound revealed a "lancet-shaped" endometrial corona, a gestational sac near the uterus base extending towards the uterine serosa, and visible interstitial lines. The patient underwent laparoscopic surgery for a lesion in the right fallopian tube. 3D-TVUS was crucial in precisely locating the gestational sac, aiding in effective treatment. Interstitial ectopic pregnancies risk severe hemorrhaging upon rupture. Rapid, accurate diagnosis is vital for lifesaving treatment and preventing critical complications.
