title: The appearance of inverted Meckel diverticulum with intussusception on air enema.
abstract: This paper presents the appearances of inverted Meckel diverticulum with an irreducible intussusception on air enema in four children. The inverted Meckel diverticulum appeared as a bulbous (3) or triangular (1) filling defect in the air column projecting off the distal end of the soft tissue mass of the irreducible intussusceptum. The bulbous defect appears to be highly suggestive, and may be specific, for inverted Meckel diverticulum. Earlier recognition of the presence of the Meckel diverticulum as the lead point of the intussusception could have changed the management in two of the children.
