Three-dimensional sonographic findings of a cervical pregnancy

A cervical pregnancy is an uncommon ectopic pregnancy that accounts for less than 1% of such gestations.(1) This condition is associated with an extremely high risk of massive hemorrhage and previously often required hysterectomy.(1) The current diagnostic modality of this potentially life-threatening condition is transvaginal sonography, supported at times by magnetic resonance imaging.(2-4) The definitive diagnostic imaging feature of a cervical pregnancy is the location of a gestational sac in the cervix in the presence of a closed internal uterine cervical OS.(2-7) We report the 3-dimensional transvaginal sonographic findings of a cervical pregnancy at 6 weeks' gestation.
