title: Gallstone ileus diagnosed by computed tomography.
abstract: We report a case of gallstone ileus in which CT was the first study to suggest the diagnosis by demonstrating an ectopic gallstone and biliary gas not visible on abdominal plain radiography. Radiologists should be aware of the CT findings in gallstone ileus, so that a more rapid preoperative diagnosis may lead to decreased morbidity and mortality in these patients.
