Necrotizing enterocolitis (NEC) is a gastrointestinal disease that mostly affects premature infants. It involves infection and inflammation that causes destruction of the bowel. Although it affects only 1 in 2,000 to 4,000 births, or between 1 and 5% of neonatal intensive care unit admissions, NEC is the most common and serious gastrointestinal disorder among hospitalized preterm infants. We present a very representative abdominal X-ray of this disease.
