Spontaneous bilateral tubal ectopic pregnancy and failed methotrexate therapy: A case report, ,

Spontaneous bilateral ectopic pregnancy is extremely rare. An unsuspected case of spontaneous bilateral ectopic pregnancy with failure of single-dose methotrexate is presented. We question whether the recommended dose of methotrexate for unilateral ectopic pregnancy is adequate for bilateral tubal pregnancy.(Am J Obstet Gynecol 1997;177:1545-6.)
