Diagnostic dilemma between angular and interstitial ectopic pregnancy: 3D ultrasound features

Y G Durand et al. J Ultrasound. 2022 Dec.

Abstract

Angular pregnancy is a rare entity which is commonly confused with interstitial or cornual pregnancies. A lack of consensus about the specific ultrasound features of these 3 entities leads to inappropriate interchange between them among the literature. An angular pregnancy should be considered as a potentially viable intra-uterine eccentric pregnancy as it might be carried to term and result in a live-born baby whereas interstitial or cornual pregnancies should be considered as ectopic pregnancies which should be interrupted. We report here two cases of women at 8 weeks of pregnancy with an angular pregnancy diagnosed by vaginal 2D and 3D ultrasound and discuss about specific ultrasound features and alternative imaging modalities to distinguish it from interstitial and cornual pregnancies.

Keywords: 3D ultrasound; Angular pregnancy; Interstitial pregnancy; Pelvic ultrasound.
