Spontaneous Bilateral Ectopic Pregnancy Treated With Combination of Methotrexate, Unilateral Salpingectomy, and Unilateral Expulsion of Pregnancy

Abstract
Spontaneous bilateral ectopic pregnancies are rare. In the majority of case reports, treatments prescribed were methotrexate, bilateral salpingectomy, or salpingectomy/salpingostomy. A 31-year-old gravida 3 para 0 at our institution underwent diagnostic laparoscopy due to ruptured ectopic pregnancy, and based on visual inspection, had a bilateral ectopic pregnancy. She underwent right salpingectomy for a ruptured ectopic pregnancy and had spontaneous expulsion of the left ectopic pregnancy with mobilization of the fallopian tube. She received methotrexate as per the two-dose protocol and was followed with a negative beta-human chorionic gonadotropin (b-hCG). Pathology confirmed bilateral tubal ectopic pregnancies. Spontaneous bilateral tubal ectopic pregnancy requires a high level of clinical suspicion. If a tubal pregnancy has expulsion of tissue intraoperatively, a two-dose protocol for methotrexate administration may be used for treatment, especially in the case of a bilateral ectopic pregnancy with fertility desires.
