Ultrasound is an important tool in the evaluation of fetal development and detection of fetal abnormalities. The ability to detect abnormalities in utero can help improve perinatal care; therefore, a detailed sonographic examination of the fetus should always be obtained. Abdominal wall defects that can be recognized by sonography include omphalocele, gastroschisis, umbilical cord hernia, and limb/body wall complex. The sonographer should attempt to give a detailed description of the defect including the organs involved, the presence of a sac, the site of cord insertion, and the presence of any associated anomalies. This information can aid the physician and parents in determining the course of management of the pregnancy.
