Ultrasonographic-RMN diagnosis of placenta previa accrete. (a) 2D transabdominal ultrasound showed the absence of placental- miometral interface, the uterine wall being undistinguishable from the placenta, and the presence of multiple vascular intraplacental lacunae "Swiss cheese placental appearance," (b) 2D color Doppler ultrasound revealed an extensive vascularity along the anterior portion of the lower uterine segment and appears to extend up to and around the bladder, (c) 3-dimensional power Doppler showed the presence of numerous retroplacental vessel, and (d) pelvic magnetic resonance (MR) confirmed the ultrasound diagnosis of placenta previa accreta with partial wall bladder invasion.

An urgent abdominal ultrasound examination showed a viable fetus with appropriate biometrical parameters and normal amniotic fluid, while transvaginal Eco-Doppler images suggested the diagnosis of placenta previa accreta (Figure 1). Careful evaluation of the placenta with pelvic noncontrast magnetic resonanceimaging (MRI) confirmed the ultrasound diagnosis (Figure 1).
