A pelvic MRI was performed on postoperative days 48 (a and b), 92 (c), and 232 (d). a and b, MRI on postoperative day 48 revealed a decrease in the size of the placenta (approximately 12 cm). Gadolinium-enhanced T1-weighted MRI revealed a diffuse lesion with variable enhancement of the placenta. The other slice of the image is shown in b. Red arrows in (b), the residual placenta that had invaded the bladder wall. c, MRI on postoperative day 92 revealed a further decrease in the size of the placenta (approximately 6 cm). Gadolinium-enhanced T1-weighted MRI exhibited no enhancement of the placenta. d, MRI on postoperative day 232 confirmed the absence of any residual placenta. With gadolinium enhancement, a small defect was observed in the uterine anterior wall
