title: Misdiagnosis of bilateral tubal pregnancy: a case report.
abstract: BACKGROUND
  The incidence of bilateral tubal pregnancy is rising due to the increase of pelvic inflammatory disease and assisted reproductive techniques. Because the clinical manifestations of bilateral tubal pregnancy are not specific, we often ignore inspection of the other fallopian tube when focusing on the lesions, which may cause misdiagnosis.
  
  
  METHODS
  A 33-year-old Chinese woman presented with vaginal bleeding after menopause and with an abnormality found by transvaginal ultrasound scan for which she underwent laparoscopy and salpingectomy. Unfortunately, she had to undergo a repetitive laparoscopic salpingotomy for the other tubal pregnancy due to misdiagnosis of her bilateral tubal pregnancy.
  
  
  CONCLUSIONS
  The incidence of unusual presentations of ectopic pregnancies has risen. Surgeons should always keep in mind the possibility of bilateral tubal pregnancy. An attentive examination of the pelvis, especially the two fallopian tubes, is necessary to avoid missing bilateral tubal pregnancy.
