A previously healthy 8-year-old male complained of severe, intermittent and stabbing abdominal pain that had waxed and waned over the past 3 days. At the time of presentation, the pain was right-sided, peri-umbilical and non-radiating. He denied nausea, vomiting, hematochezia, melena or urinary tract symptoms; he had however experienced several recent episodes of brown diarrhea.
The target sign is classic for intussusception on both CT and ultrasound. Its appearance is attributed to the different densities of tissue layers that are apposed to each other by the telescoping bowel, and when the luminal diameter is increased, intussusception must be considered in the differential diagnosis . Although most cases of intussusception are idiopathic, there have been several case reports of Meckel’s diverticulum serving as a lead point [2–4].
