Colonic hyperganglionosis presenting as neonatal enterocolitis and multiple strictures

Neuronal intestinal dysplasia (NID) usually mimics Hirschsprung's disease, but rarely presents as neonatal enterocolitis. The authors report a case of colonic hyperganglionosis, which is a form of NID, presenting with postenterocolitis intestinal strictures. NID should be considered as a possible (although rare) cause of neonatal enterocolitis and may present with intestinal strictures.
