title: Hepatobiliary imaging in gallstone ileus.
abstract: Hepatobiliary imaging was performed in a woman who, at subsequent surgery, was found to have gallstone ileus due to a large gallstone obstructing the proximal jejunum. The triad of findings (failure of the radiopharmaceutical to pass beyond the point of obstruction, marked reflux into the stomach, and nonvisualization of the gallbladder) is nonspecific but, in the appropriate clinical setting, should suggest the possibility of gallstone ileus.
