Inverted Meckel's diverticulum as a leading point of intussusception: Computed tomography manifestation

Meckel's diverticulum is the most common omphalomesenteric duct anomaly and occurs on the anti-mesenteric border of the distal ileum. An inverted Meckel's diverticulum is the most common pathologic leading point of intussusception in children and needs emergent operation. However, it is still a challenge to differentiate which children may have intussusceptions due to pathologic leading points from those who have idiopathic intussusceptions. Imaging plays an important role for diagnosis, because the varied and often nonspecific presentation and the wide spectrum of types of pathologic leading points. The frequent diagnostic modalities include conventional barium study, sonography, radionuclide Meckel scan, computed tomography and angiography. The aim of this report is to demonstrate the role of computed tomography (CT) in diagnosing intussuscepted Meckel diverticulum.
