The initial transabdominal ultrasonography images show a gestational sac (bold arrow) located anteriorly in the lower uterine cavity with an empty uterine endometrial cavity (narrow arrow) (a). The color/power Doppler images depict a hyperechoic rim of choriodecidual reaction with excessive vascularity (b). The computed tomography image shows an intrauterine gestational sac in the lower uterine segment bulging through the anterior uterine wall at the site of the cesarean scar without invasion of the urinary bladder (c, d)
