An ectopic pregnancy is defined as cesarean scar pregnancy (CSP) when the products of conception are implanted within the myometrium in the area of a cesarean section scar. CSP can be a life-threatening condition and to date there is no clear consensus for CSP management. A medical approach joining high treatment rates with fertility preservation could be a safer and less invasive method of therapy.We present a case of CSP with a viable embryo that was successfully treated with a novel medical therapy combining multidose methotrexate (MTX) and mifepristone.No further additional invasive procedure was required since pregnancy products were dissolved and no major complications were experienced.Multidose MTX and mifepristone can be considered a safe and effective treatment for CSP.
