Gastrointestinal obstruction by a gallstone is an uncommon but important complication of biliary stone disease which
mostly affects the elderly. The classic triad of radiological features includes pneumobilia, ectopic gallstone and evidence
of intestinal obstruction. Terminal ileum is the most common site of obstruction, followed by jejunum and gastric
outlet. We present a case of duodenal gallstone ileus of a large, fluid-density mixed biliary stone with a peripheral rim
of hyperdensity (very fine calcification) in CT scan.
