title: Didelphic uterus and unilaterally imperforate double vagina as an unusual presentation of right lower-quadrant abdominal pain.
abstract: Imperforate hymen should be considered in girls of menarcheal age with a history of amenorrhea and vague abdominal discomfort, particularly if associated with symptoms of urinary obstruction or constipation. Patients may present with severe dysmenorrhea and localized pain mimicking appendicitis if hematocolpometra is due to unilaterally imperforate hymen with duplicate vagina and didelphic uterus. Although this condition is exceedingly rare, the case presented stresses the importance of a careful history and physical examination of an adolescent girl presenting with symptoms of abdominal pain associated with menstruation.
