Intussusception in an eleven years old girl: the diagnostic challenge in an unusual age

Intussusception is considered the most common cause of intestinal obstruction in infants between 6 and 36 months of age, consisting of the invagination of an intestinal tract into itself. This condition is considered rare in older infants and young adults, where the diagnosis is commonly overlooked and usually underlines a para physiologic or pathologic mass serving as a lead point for invagination. On sporadic occasions a Gastrointestinal duplication can be identified by the pathologist.
