Ultrasound (A, B, C) images, showing differentiation of cesarean scar pregnancy (CSP) according to position of the gestational sac (GS) in relation to the uterine cavity line (UCL) and serosal contour. A: Type I CSP. This image shows that the largest part of the GS, is located behind the UCL, protruding into the uterine cavity. B: Type II CSP. This image shows that the largest part of the GS, is located in front of the UCL, protruding into the anterior uterine wall and the GS does not extend beyond the serosal contour. C: Type III CSP. This image shows that the largest part of the GS, is located in front of the UCL, protruding into the anterior uterine wall and the GS extends beyond the outer contour of the uterus
