[edit] Discussion

  • Invaginating portion of the intestine (intussusceptum) invaginates into the receiving portion of the intestine (intussuscipiens).
  • Common cause of childhood intestinal obstruction.
  • A seasonal variation exists in some groups with a higher incidence in fall and spring
  • It occurs more frequently in males than in females.
  • Intussusception typically occurs in children aged 6 months to 2 years.
  • In neonates or in children older than 2 years, intussusception has a high incidence of associated bowel abnormality that serves as an initiating lead point.
  • Transient intussusceptions are sometimes identified and generally have no real clinical significance. These shoud be distinguished from more severe forms requiring surgical treatment.
  • Example of lead points

[edit] Imaging Findings

  • May be normal
  • Dilated small bowel and absence of gas in the region of the cecum.
  • Occasionally, a mass impression within the colonic gas indicates an intraluminal mass created by the intussuscepting loop
