Uroepithelium in a colonic diverticulum.
Giant colonic diverticula are rare entities and often present in adulthood as acute diverticulitis. The authors present a case of giant colonic pseudodiverticulum lined with uroepithelium causing bowel obstruction in a neonate. The presence of uroepithelium in a colonic pseudodiverticuium remains unexplained and to the authors' knowledge unreported. This heterotopic tissue may be a result of an embryonic rest or could be urachal in origin adhering initially to the colon and eventually detaching from the umbilicus. These lesions should be resected because of the risk of infection, perforation, or obstruction.
