Intussuscepted Meckel diverticulum: radiologic-pathologic correlation.

Nine cases of Meckel diverticulum presenting with intussusception were reviewed and correlated clinically, radiologically and pathologically. The appearance of intussuscepted Meckel diverticulum by small bowel series is not specific. However, by CT, a central fat density surrounded by a thick collar of soft tissue was noted in one case correlating well with the gross pathologic appearance. The pathologic material in all our cases suggests that this CT appearance is characteristic of an inverted Meckel diverticulum.
