[Placenta percreta with bladder invasion: an uncommon cause of hematuria during pregnancy].

Placenta percreta with bladder invasion is a very uncommon condition that can lead to very severe complications in pregnant women. Although it is often diagnosed during delivery, imaging techniques are very useful for early diagnosis, which is fundamental for planning surgery and avoiding potentially lethal complications. We present the case of a woman with a history of cesarean section who presented with hematuria and low back pain. The diagnosis of placenta percreta with bladder invasion was suggested after ultrasonography and magnetic resonance imaging and was confirmed at surgery. We provide a brief review of the literature, emphasizing the role of imaging techniques.
