The incidence of the placental invasion anomalies are increasing, mainly due to repeat cesarean deliveries. Placenta percreta occurs if these villi perforate the serosa and also sometimes into adjacent organs such as the bladder. The prenatal diagnosis is very important because of the high maternal morbidity and mortality rates without the appropriate surgical planning. The adherent placentas will result in severe early postpartum bleeding, just after the delivery of the fetus. Severe hemorrhage usually results rapidly in disseminated intravascular coagulation (DIC), shock, multiorgan failure or death.The surgery is also challenging due to the risk of the adjacent tissue damage, such as bladder or ureteral injury. Approximately 1 in every 3 cases need intensive care. We present here a prenatally diagnosed, 31-year-old gravida 7 para 2 abortus 4 pregnant case with placenta percreta and rewiev the relevant literature about the key aspects in the ultrasonograhic diagnosis and underlie the key points in the diagnosis.
