Report of two cases of uterus didelphys and rare ectopic (cornual and cervical) pregnancies.

Two cases of rare ectopic pregnancies are presented, both with underlying uterine didelphys anomaly. Uterine anomalies are a well-known predisposing factor for ectopic pregnancies. Detection of the uterine anomaly is crucial in the choice of treatment of an ectopic pregnancy as well as planning of future pregnancies. Magnetic resonance is helpful in diagnosing and defining the uterine anomaly (Saleem S. MR imaging diagnosis of uterovaginal anomalies: current state of the art. Radiographics 2003; 23:e13) that should be suspected by ultrasound.
