[Solitary diverticulum of ascending colon induced internal intestinal herniation: report of one case].

Colonic diverticula are generally multiple and occur most commonly in the descending and sigmoid colon. Solitary ascending colonic diverticulum is a rare pathology and presents several features which separate it from colonic diverticulosis. It is a true diverticulum. It is a congenital dysplasia that generally runs an asymptomatic course and becomes clinically important only when inflammatory, perforating, or hemorrhagic complications occurs and presents a difficult problem in diagnosis and management. An unusual case of 4 year old girl with solitary ascending colonic diverticulum was reported here. It caused internal intestinal herniation by forming an adhesion band with mesentery and the clinical course manifested as an acute intestinal obstruction.
