Intestinal dilatation and hyperechogenic bowel, some typical ultrasonographic features of anorectal malformation, were found in the 21st week of a singleton pregnancy. These findings were associated with unilateral renal agenesis and a single umbilical artery.
All prenatally diagnosed anomalies were confirmed postpartum. Development of the sonographic appearance of the anorectal malformation, prenatal and neonatal management are described and discussed.
