2022年12月5日 · Angular pregnancy occurs when the blastocyst is implanted in the lateral angle of the endometrial cavity, medial to the uterotubal junction and round ligament 1. In contrast, an interstitial ectopic pregnancy is located more laterally within the interstitial segment of the Fallopian tube which courses within the myometrial wall.

Radiologists and sonographers should be aware of the sonographic diagnosis of angular, cornual and interstitial pregnancies. Whenever possible, first-trimester transvaginal ultrasound scanning is crucial for diagnosing these 3 types of ectopic pregnancies in the cornual region.

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.

2020年5月4日 · We advocate the use of early first trimester ultrasound to correctly differentiate between eccentric pregnancy and interstitial ectopic pregnancy as current research suggests substantially better outcomes with correctly diagnosed and expectantly managed eccentric pregnancies than past investigations may have shown.

2023年3月1日 · An additional ultrasound technique used to differentiate interstitial ectopic, and angular pregnancies is the endomyometrial mantle thickness (See Fig 2). An endomyometrial mantle thickness of <5mm is highly suspicious for interstitial ectopic pregnancy.

In the two angular pregnancy cases, transvaginal ultrasonography was employed to confirm the diagnosis, which showed a lack of the interstitial line sign, contiguity of the decidua and endometrium, and an endomyometrial mantle thickness between 5 and 8 mm.

2024年7月12日 · This report discusses two cases of 8-week angular pregnancies diagnosed via vaginal 2D and 3D ultrasound, highlighting the importance of distinguishing it from other types using specific ultrasound features and alternative imaging modalities.

2014年5月2日 · Angular pregnancy is defined as a pregnancy implanted in one of the lateral angles of the uterine cavity. It has been classified as ectopic, nearly ectopic, or intrauterine. Unlike an interstitial pregnancy, which implants in the intramural portion of the fallopian tube, an angular pregnancy can progress to term.

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.

2019年1月1日 · In our 2 cases, a combination of transvaginal and 3-dimensional ultrasound images provided assistance in the accurate diagnosis of angular ectopic pregnancies. Traditional management of these pregnancies includes a wedge resection for pregnancy resolution.
