Intussusception is a medical emergency that occur with higher frequency in children under 2 years of age. Diagnosis can be difficult as the classical triad of abdominal pain, jelly stools and palpable abdominal mass is seen in less than 50% of the patients. However, the diagnosis of intussusception can be established with variable degree of accuracy using plain abdominal x-ray films, ultrasound, computed tomography or barium (or air/saline) enema. Some of these imaging methods are also useful during treatment of this condition. The authors present a review of the literature and a pictorial essay of the imaging findings in patients with intussusception. In addition, a discussion on the current and controversial issues related to the treatment of intussusception is presented.
