Internal hernia as cause of acute abdomen in a preterm neonate: when necrotizing enterocolitis is not the culprit.

Internal hernias in preterm neonates, although rare, can arise due to various anatomical and physiological factors associated with prematurity. We report a case of a preterm infant with symptoms of suspected necrotizing enterocolitis (NEC) that turned out to be an internal hernia during surgical exploration. Given the overlapping symptoms, it is crucial to maintain a high index of suspicion and utilize the appropriate imaging techniques, such as ultrasound or radiographic studies, to aid in the differentiation between NEC and internal hernia, especially when responding to cases that do not improve with standard NEC management or exhibit atypical features. Early recognition and accurate differentiation are crucial for appropriate management and prevention of complications in affected neonates.
