Gallstone liens with impaction at the neck of a Meckel's diverticulum

We report a case of gallstone ileus in which the stone impacted at the neck of a Meckel's diverticulum. CT demonstrated the gallstone as a calcified m ass in the lower abdomen. Gallstone ileus was diagnosed although a more acc urate diagnosis was not obtained pre-operatively. The site of impaction was not typical and a blind loop filled with contrast material was evident. We believe that this is the first report demonstrating this rare condition wi th imaging.
