title: Spontaneous bilateral tubal ectopic pregnancy and failed methotrexate therapy: a case report.
abstract: 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.
