Omental Infarction in Pediatric Patients: Sonographic and CT Findings

Children with omental infarction typically present with abdominal pain and are diagnosed clinically as having acute appendicitis. Our purpose was to perform a retrospective review of the imaging findings in nine children with omental infarction as an aid to radiologists in distinguishing this entity from acute appendicitis. In pediatric patients with omental infarction, both CT and sonography show a heterogeneous mass characteristically situated between the anterior abdominal wall and the colon. It is important for radiologists to recognize the characteristic imaging findings seen with omental infarction.
