The most common site of ectopic implantation of a fertilized embryo is the fallopian tube. In extremely rare situations, the embryo can implant in other locations, which makes the diagnosis and management even more complex. Although close observation of a new pregnancy is key in the diagnosis and treatment of an ectopic pregnancy, there is still a major risk of life-threatening outcomes. This is a case report of a 31-year-old patient with a history of multiple pregnancies who presented to a community hospital in the spring of 2021 with an ectopic caesarean scar pregnancy. A diagnosis of ectopic pregnancy was on a timely basis, and surgical management was advised. Upon refusal of treatment and admission, pharmacological management was initiated, but patient compliance challenged the success of the therapy. Patient non-compliance to close follow-up resulted in a ruptured uterus. Emergency laparotomy with supracervical hysterectomy was performed as a life-saving procedure.Keywords: Ectopic pregnancy, caesarean section scar ectopic, methotrexate, compliance
