title: Gallstone ileus with impaction at the neck of a Meckel's diverticulum.
abstract: 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 mass in the lower abdomen. Gallstone ileus was diagnosed although a more accurate diagnosis was not obtained pre-operatively. The site of impaction was not typical and a blind loop filled with contrast materials was evident. We believe that this is the first report demonstrating this rare condition with imaging.
