Gallstone ileus is a rare cause of mechanical small bowel obstruction due to gallstone impaction within the lumen of the small intestine after passing through biliary enteric fistula. We report a case of gallstone ileus that was diagnosed with Rigler's triad (small bowel obstruction, ectopic gallstone, pneumobilia) in abdominal contrast-enhanced CT scan that is less than 30% of the patients.
Key words: Gall stone, Ileus, small bowel obstruction, pneumobilia, Rigler's triad.
