MRI of placenta increta (third pregnancy).. Notes: Coronal T2 MRI of the abdomen showing an irregular-looking posterior placenta, thinning of the myometrium, and discontinuity of the posterior uterine wall. A sigmoid loop (indicated by the arrow) is observed adjacent to the posterior uterine wall, however, it seems not to be invaded by the placenta. No dilation of the proximal or distal intestine was detected.. Abbreviation: MRI, magnetic resonance imaging.

Magnetic resonance imaging (MRI) performed at 21 weeks' gestation demonstrated placental tissue penetrating, but not perforating, the myometrium of the posterior uterine wall, which was indicative of placenta increta (Figure 1).
MRI of placenta percreta (fourth pregnancy).. Notes: (A) Coronal T2 MRI of the abdomen showing an irregular-looking posterior placenta, thinning of the myometrium, and discontinuity of the posterior uterine wall (arrows) with abnormal vascularity and prior hemorrhages (dashed arrow). (B) Placenta penetrating through 5x2 cm uterine wall rupture in the left cornu (arrow), as observed during the surgery.. Abbreviation: MRI, magnetic resonance imaging.

This suspicion raised by sonography, together with the patient's history, prompted an MRI at 24.2 weeks that demonstrated the presence of placenta percreta at the site of the previous placenta increta (Figure 2A). During laparotomy, massive intraabdominal bleeding was observed, originating from a uterine rupture with a perforating placental tissue (Figure 2B).
