Inversion is a potentially serious complication of Meckel diverticulum
. Since inversion provokes gangrene and small bowel obstruction, diagn

timely surgical intervention. We have noted that plain films may pred
ict this lesion when a solitary mottled polypoid lesion occupies the i
leum at the site of a small bowel obstruction.
