title: Rudimentary horn pregnancy with herniation into the main uterine cavity.
abstract: We report a case of a rudimentary horn pregnancy with herniation of a fetal arm and umbilical cord into the main uterine cavity that presented as an incidental finding on a routine second-trimester ultrasound scan. We also review the literature that guides the diagnosis and management of these rare complicated pregnancies.
