Prenatal diagnosis of prune belly syndrome at 12 weeks of pregnancy: case report and review of the literature.

Abstract

We present a case of prune belly syndrome in a 12-week fetus whose previous anomaly scan at 10 weeks had been normal. The ultrasound diagnosis was based on the findings of a lower abdominal cystic echo caused by abnormal dilatation of the bladder. Termination was performed at 14 weeks and autopsy confirmed the distended bladder. In addition, there was bilateral hydronephrosis and an absence of abdominal muscles, liver, spleen and diaphragm. A review of the literature indicates that ours may be the earliest reported case of prune belly syndrome.
