A neonate has a large anterior abdominal wall defect with herniated abdominal contents covered by a transparent sac. The umbilical cord inserts into the apex of the sac. The most likely diagnosis is:

• A Omphalocele ✓
• B Gastroschisis
• C Prune belly syndrome
• D Umbilical hernia

Explanation

Omphalocele is characterized by herniated abdominal contents covered by a sac composed of peritoneum and amnion, with the umbilical cord inserting at the apex. It is associated with other anomalies in over 50 percent of cases, including cardiac defects, Beckwith-Wiedemann syndrome, and chromosomal abnormalities. Gastroschisis is a full-thickness defect to the right of the cord without a covering sac. Umbilical hernia is a small fascial defect covered by skin.
