{Abstract}: The incidence of ectopic pregnancy (EP) is 1.3-2.4%. Suspicion of EP starts after a positive serum pregnancy test and failure to visualize the intrauterine gestational sac (GS) by transvaginal sonography (TVS). About 88% of tubal EPs are diagnosed by absent intrauterine GS and the presence of an adnexal mass during TVS. Medical treatment of EP using methotrexate (MTX) is cost-effective with a similar success rate to surgical treatment. The presence of fetal heart beats, β-human chorionic gonadotropin >5000 mIU/mL, and EP size >4 cm are relative contraindications for using MTX in the treatment of EP.
