Unilateral Twin Ectopic Pregnancy in a Patient With a History of Multiple Sexually Transmitted Infections

[摘要] Background. The incidence of unilateral twin ectopicpregnancy is a rare condition. Several factors increase the riskof ectopic pregnancy, the most important of which is pelvicinflammatory disease, followed by operative trauma, congenitalanomalies, tumors, and adhesions resulting in anatomicallydistorted fallopian tubes. We present a case of a woman with ahistory of four confirmed sexually transmitted infections (STIs)includingChlamydia trachomatis, Neisseria gonorrhoeae,herpes simplex virus 2, andTreponema pallidum. The caseillustrates the potential impact of sexually transmittedinfections (STIs) on the risk of a twin ectopic pregnancy.Case. A 24-year-old primigravida, presented with anunknown last menstrual period, lower abdominal pain, wateryvaginal discharge, and vaginal spotting. During thishospitalization, serumβ-HCG testing was 263 mIU/mL andtransvaginal ultrasonographic examination suggested a nonviableunilateral twin ectopic pregnancy. At exploratory laparotomy, a10 cm mass involving the right fallopian tube and ovary wasexcised. Pathological evaluation of the specimen identified amonochorionic, diamnionic twin ectopic pregnancywithin the fallopian tube.ConclusionsPatients with ahistory of multiple (STIs) are known to be at risk for thedevelopment of chronic pelvic infection and postinflammatoryscarring. The resulting distortion of the normal tubal anatomyleads to an increased risk of an uncommon presentation of ectopicpregnancy.
