Term angular pregnancy: Successful expectant management

Interstitial pregnancy sometimes is mistakenly referred to as cornual pregnancy and is frequently confused with angular pregnancy. A strict distinction among these three conditions is clinically important because their findings, management and outcomes are different. We report an unusual case of pregnancy where interstitial pregnancy was diagnosed at 6 weeks of pregnancy, located close to the right cornual portion of the uterus. Prenatal monitoring was carried out until birth at 36 weeks' gestation with uterine conservation. Ultrasound scan and magnetic resonance imaging were realized to confirm the diagnosis and to monitor the evolution.
