title: Unilateral twin tubal ectopic pregnancy in a patient following tubal surgery.
abstract: We report a spontaneous unilateral live tubal twin pregnancy in a patient with a history of previous ectopic pregnancy (EP) and tubal surgery. Transvaginal ultrasound showed one pregnancy sac containing two fetal poles with cardiac activity, which appeared to be sited within the right adnexum. The right tubal EP was removed by salpingectomy. Ultrasound findings of suspected adnexal mass and free liquid in the Douglas pouch along with an increased a beta-human chorionic gonadotrophin levels, especially in association of risk factors, can help the early diagnosis of EP and reduce the related mortality and morbidity.
