Vomiting and food refusal causing failure to thrive in a 2 year old: an unusual and late manifestation of congenital duodenal web.

Congenital duodenal anomalies like atresia, stenosis and web or diaphragm commonly present in the neonatal age with signs of intestinal obstruction. Duodenal webs can sometimes present in early infancy and very rarely beyond infancy. The authors present a case of congenital duodenal web with a very small central aperture in a 2-year-old child with presenting features of persistent vomiting and resultant failure to thrive without any overt signs of intestinal obstruction.
