Ultrasonography features of scar ectopic pregnancy include empty uterus and cervix with normal endometrium and endocervical canal, gestational sac (with embryo and\/or yolk sac) in the anterior part of the lower uterine segment in the region of the Caesarean scar with a thin myometrial layer between the bladder wall and gestational sac. Magnetic resonance imaging may be used as an adjunct imaging modality in cases with inconclusive or equivocal sonographic findings. Termination of pregnancy in the first trimester should be considered and treatment options should be individualized as there is no universal agreement on the best or most preferred treatment modality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Awareness of specific
