Correct Answer: Peyer's patch hypertrophy
Description: Pathogenesis of intussusception
Between the age of 3 to 9 months, the cause of acute intussusception is idiopathic.
It is postulated that gastrointestinal infection or the introduction of new food proteins result in swollen Peyer's patches in the terminal ileum. The prominent mounds of tissue leads to mucosal prolapse of the ileum into the colon thus causing an intussusception.
In 2-8% of patient, recognizable lead points for the intussusception are found, such as a Meckel's diverticulum, intestinal polyp, neurofibroma, intestinal duplication, hemangioma or malignant condition such as lymphoma.
