Congenital pouch colon syndrome is partial or complete replacement of the colon by a pouch-like structure and anorectal malformation. Commonly reported from northern India, we believe this is the first report of congenital pouch colon syndrome in a Saudi Arabian neonate. He was referred with an imperforate anus and diagnosed as having a high anorectal malformation. The patient underwent a sigmoid colostomy. Continued abdominal distension after the colostomy prompted sonography and computed tomography, which showed an air- and fluid-containing cystic structure in the abdomen.
