Semicircular stenosis, thought to influence adhesions in the uterus, was confirmed, and amniotic membrane sheets (tissues with a free edge visualized within the amniotic cavity) were identified (arrow).

At 19 weeks of gestation, tissues with a free edge were visualized within the amniotic cavity using obstetric ultrasound and were determined to be amniotic sheets on MRI at 31 weeks of gestation (Figure 1).
Intraoperative finding: blood vessels on the uterine surface at the placental implantation site are engorged.

The blood vessels on the uterine surface at the placental implantation site were engorged (Figure 2), leading us to diagnose the patient with placenta increta.
Resected uterus: placenta is present from the fundus to the posterior uterine wall. The placenta adheres diffusely to the myometrium, and partial thinning is visible at the fundus.

Macroscopic examination of the uterus after extraction showed the presence of placenta from the fundus to the posterior wall, diffusely adherent to the myometrium (Figure 3), along with partial thinning of the fundus.
