title: Bilateral tubal pregnancy after natural conception: a case report.
abstract: BACKGROUND
  Bilateral tubal pregnancy is very rare and usually follows ovulation stimulation.
  
  
  METHODS
  A 36-year-old woman with acute pelvic pain underwent emergency laparoscopy for suspected left ruptured tubal pregnancy. Bilateral hematosalpinx with a ruptured left tubal pregnancy and active bleeding from the right fallopian tube was noted during surgery, and bilateral salpingectomy was performed by laparoscopy. Pathologic examination of the left tube confirmed the presence of conception products and trophoblastic tissue. The right salpingectomy specimen contained some trophoblastic tissue resembling an earlier tubal pregnancy encased in a cyst.
  
  
  CONCLUSIONS
  This was a rare case of spontaneous bilateral tubal pregnancy after conception at different times. The explanation of the presentation is uncertain. Laparoscopy remains the cornerstone of diagnosis and treatment in the majority of women with a tubal pregnancy; this is especially true in complex cases, such as bilateral tubal pregnancy.
